Boiler Usage Guide |Industrial Thermal Oil Boiler Common Malfunction and Solution

May 10, 2022

Thermal oil boiler is a boiler that uses thermal oil for heating. General thermal oil boilers are used in petroleum, asphalt, steel and other items that require high temperature heating and corresponding enterprises. Compared with traditional heating boilers, Thermal oil boilers have higher system heat utilization, simpler and more convenient maintenance, and Thermal oil boilers generally have a longer service life than traditional oil boilers, so they are more favored by heat-using enterprises.

 

Industrial Thermal Oil Boiler Working Principle and Advantages

 


The thermal oil boiler is a heating boiler manufactured based on the forced circulation design idea. The heating process of the Thermal oil boiler uses the thermal oil as the medium to burn the fuel. The medium, that is, the thermal oil, is recirculated and reheated.

 

Therefore, the thermal oil boiler can achieve full utilization of resources. It obtains high temperature in a low pressure environment. On the one hand, it has good safety during the heating process, and on the other hand, it can achieve high temperature operation.

 

Although the thermal oil boiler is more comprehensive than other traditional boilers, and has been greatly improved in performance, quality, safety and other aspects, but as the Thermal oil boiler is used more and more widely, and due to the thermal conductivity Oil boilers work in a high temperature environment for a long time, and they are still operated manually, so it is inevitable that some problems and failures will occur.

 


Based on decades of research on thermal oil boilers and deep ploughing of user sites, EPCB analyzes the process of using thermal oil boilers by enterprises. common malfunction of thermal oil boilers are: burst pipes, bulging, bumping fuel injection, and thermal oil. Leaks, lack of water in the evaporator, etc.

 

In order to ensure the normal and efficient heating of the Thermal oil boiler, and to ensure the safety of the staff, the relevant departments need to pay enough attention to the failure of the Thermal oil boiler. EPCB conducts in-depth analysis and research on the common malfunction of the Thermal oil boiler , and put forward some methods and measures to eliminate and deal with common malfunction of Thermal oil boilers, so as to ensure that Thermal oil boilers can operate and work normally and efficiently.

 

Industrial Thermal Oil Boiler Common Malfunction

 


The pipe of the Thermal oil boiler has burst pipes and bulges

 

Since the Thermal oil boiler needs to work for a long time under high temperature conditions, if the staff does not control the temperature well, the temperature exceeds the normal temperature, and the thermal oil is deteriorated at the same time. In this case, the thermal pipe of the Thermal oil boiler or The phenomenon of other working parts bursting and bulging is faulty.

 

The occurrence of failures such as burst pipes and bulges will seriously affect the thermal conductivity of the Thermal oil boiler and the normal operation of the process of fuel transmission and thermal circulation, which will reduce the working efficiency of the Thermal oil boiler to a certain extent.

 

Bumping and spraying of thermal oil

 

Thermal oil is the most important part of the thermal oil boiler. It is prone to deterioration when it is in a high temperature environment for a long time. If the temperature of the thermal oil is too high, or even exceeds the normal temperature; there is no good transition and buffering process for the rapid heating and rapid cooling of the thermal oil, which will cause the thermal oil to heat up and cool down too quickly. 


If the thermal oil is mixed with some Water and thermal oil will have bumping, spraying and other faults during the working process. If the thermal oil boils and is sprayed on the body of the staff, it will endanger the life safety of the staff, and even cause a fire in serious cases, resulting in more serious negative effects and consequences. The bumping of the thermal oil will affect the working quality of the thermal oil, which will greatly reduce the working efficiency of the thermal oil boiler.

 

Thermal oil leak

 

The thermal oil boiler is a working system composed of a variety of equipment parts. If there is a connection error between the various equipment, or the connection is loose due to long-term work, the tightness of some sealing devices is reduced, and the thermal oil will appear. The occurrence of leakage accident.


If the thermal oil leaks from the Thermal oil boiler and contaminates the body of the staff, it will endanger the life safety of the staff, and even cause a fire, resulting in more serious negative effects and consequences. If the thermal oil leaks, the amount of thermal oil will be far lower than the demand of the thermal oil work site, which will affect the working efficiency of the Thermal oil boiler, and even cause the Thermal oil boiler to fail to operate normally.

 

Thermal oil boiler Evaporator overpressure and water shortage

 

The evaporator is an indispensable part of the thermal oil boiler. It can achieve the cooling effect of the thermal oil boiler through the evaporation of water, which can keep the thermal oil boiler in a good working environment for a long time and ensure the normal operation of the thermal oil boiler operate.


1.If the automatic adjustment system of the evaporator fails, it will lead to overpressure of the evaporator;


2. If there is a problem with the water supply system of the evaporator or its automatic adjustment system fails, it will cause the evaporator to lack water.


The overpressure of the evaporator and the lack of water will cause the evaporator to not be able to cool down and dissipate the heat of the thermal oil boiler normally, so that the efficient operation of the thermal oil boiler cannot be guaranteed.

1. Establish and improve the supervision and management system

 


In order to reduce and avoid the occurrence of thermal oil boiler failures, relevant departments of the enterprise need to establish a sound supervision mechanism and management system to reasonably supervise and manage the quality and operation process of thermal oil boilers, as well as the work process of related staff. .

 

Effectively manage the relevant staff of the thermal oil boiler, and establish a sound and perfect management system.

 

1. Strict management of the staff and related work requirements can enable the staff to perform their duties with due diligence and complete the work they should do more efficiently, thereby reducing some failures of the thermal oil boiler caused by the human error of the staff.

 

2. Establish a sound and perfect supervision system, strictly supervise the operation process of the thermal oil boiler, and also strictly supervise the work process of the staff of the thermal oil boiler, so that the thermal oil boiler can be found in time. failure.

 

3.While the management system and the supervisory mechanism work independently, they must maintain communication and conduct some exchanges and cooperation.

 

In this way, the "two-pronged approach" of the management system and the supervision system will achieve a multiplier effect, allowing the thermal oil boiler and the staff related to the thermal oil boiler to operate and work more efficiently, reducing and avoiding some controllable mistakes and failures.

 

For example, in order to avoid and reduce the occurrence of some failures, the working department of the thermal oil boiler can establish a sound and complete supervision and management system to effectively supervise and manage the operation process of the thermal oil boiler and the work process of the thermal oil boiler related staff.


A perfect supervision and management system cannot be achieved by one or two people, but requires the joint efforts of many people, and everyone performs their own duties to establish a sound supervision and management system.

 

To establish a sound management system, first of all, it is necessary to require the staff involved in the management to have a full understanding and mastery of the structural composition, working characteristics, common faults and causes of the thermal oil boiler, and the work content of the relevant staff of the thermal oil boiler. Have a certain understanding, assign personnel, and carry out strict requirements and management of the work of thermal oil boiler related staff.

 

To establish a sound supervision and management system, it is necessary to:

1. Dispatch relevant personnel to effectively supervise the work of the thermal oil boiler and the work process of the thermal oil boiler related staff;

2. It is necessary to find out the working failure of the thermal oil boiler in time, as well as the mistakes of the relevant staff of the thermal oil boiler should be pointed out in time, and the staff who have made mistakes should be criticized and punished accordingly.

3. Staff can be organized to carry out professional training in relevant aspects to enhance the professional skills and working ability of relevant staff of thermal oil boilers.

4. Deal with the faults in time, so as to reduce the occurrence of some losses, and also avoid the occurrence of some casualties.

 

Under the strict requirements and careful supervision of the supervision and management system, the fault can be effectively checked, and the fault can be dealt with and solved in a timely and effective manner after the occurrence of the fault, which can not only ensure the efficient operation of the thermal oil boiler, but also can To avoid some serious losses and consequences, to a certain extent, the life safety of the staff can be guaranteed.

 

2. Strictly standardize the work flow of thermal oil boiler

 


The use of thermal oil boilers has certain operating procedures. If the operation is not carried out in accordance with the relevant work procedures, it will lead to some failures of the thermal oil boilers.

 

For example: if water is added to the thermal oil, the thermal oil will be boiled and sprayed, which will seriously affect the normal operation of the thermal boiler and affect the life safety of the staff. It can be seen that in order for the thermal oil boiler to work normally and efficiently, it must be operated in strict accordance with the prescribed work flow.

 

For example: the enterprise should dispatch relevant technical guidance or professionals to provide professional guidance to the work of the relevant staff of the thermal oil boiler to ensure that the staff can understand the standardized operation process.

 

In addition, punishment and criticism shall be given to those staff who do not operate in accordance with the regulations, verbal warnings shall be given to those whose circumstances are not serious, and those with serious circumstances shall be punished more severely, such as fines, salary deductions, etc. Rebates, etc. And for these staff who do not operate in accordance with the regulations, relevant professional training should be carried out to improve their relevant professional knowledge and work ability, and professional technical experts can be hired to explain the training. 


In this way, the work process of the relevant staff of the thermal oil boiler can be strictly regulated, and the staff can operate the thermal oil boiler in strict accordance with the requirements of the specification, thereby avoiding and reducing the failure of machinery and equipment caused by irregular human operation. question.

 

3. Regular inspection and maintenance of thermal oil boiler

 


The thermal oil boiler needs to be in a high temperature environment for a long time, and the work consumption is particularly large. Therefore, some equipment and parts of the thermal oil boiler will be aged, damaged, etc., which will lead to some failures of the thermal oil boiler, and will seriously affect the life safety of the relevant staff.


For example: poor connection of the thermal pipe of the thermal oil boiler, loose parts, and unqualified sealing of the thermal pipe may lead to the leakage of the thermal oil, which will affect the normal operation of the thermal oil boiler. May cause harm to human life.

For example: the relevant departments in the enterprise should dispatch staff to conduct regular inspections of the thermal oil boiler, and timely repair and replace the aging and damaged components to eliminate the failure of the thermal oil boiler, thereby ensuring the normal operation of the thermal oil boiler.

 

Conclusion

 

With the development of petroleum and construction industries, it is necessary to heat petroleum, asphalt, steel, etc. at high temperature, so thermal oil boilers have been used more and more. With the widespread use of thermal oil boilers, the failure of thermal oil boilers also occurs. 


Therefore, in order for the thermal oil boiler to operate normally and efficiently, relevant departments should establish a sound management and supervision system, strictly regulate the work flow of the thermal oil boiler, and carry out regular inspection and maintenance of the thermal oil boiler to reduce, eliminate and avoid the thermal oil boiler failure.
