Under the background of global manufacturing industry's continuous promotion of energy conservation and sustainable development, biomass energy is becoming an important thermal energy solution for more and more industrial enterprises. Especially in the wood processing industry, enterprises will produce a large number of combustible wastes such as sawdust and scraps in the production process. If these resources can be effectively utilized, not only can the energy cost be reduced, but also green production can be realized.
In May 2025, EPCB boiler successfully provided a set of 3 million kcal vertical wood-burning heat transfer oil boiler system for a large wood processing enterprise in Bangladesh, which was used for stable heating of the production line. This project not only solved the long-term energy cost problem faced by customers, but also became another typical successful case of EPCB boiler in the application field of biomass energy in Bangladesh.
Project Background: Wood Processing Enterprises Urgently Need Stable Heat Sources.
Bangladesh's wood processing industry has developed rapidly in recent years, and the number of furniture manufacturing, board production and wood processing enterprises has continued to grow. Such enterprises often need stable, high-temperature and continuous heat sources in the production process, such as:
Board pressing and drying
Plywood production process heating
Wood drying system
Surface treatment and hot pressing process
Although the traditional steam system can provide heat energy, in some production processes, the heat transfer oil system has the advantages of higher temperature, more stable heat energy output and lower operating pressure, so it has gradually become the first choice for many wood processing enterprises.
This customer needs a continuous and stable high-temperature heat source in the production process, and hopes to reduce the energy cost as much as possible. Because a large amount of wood scraps and sawdust will be produced in the production process of enterprises, customers hope to realize energy recycling by burning these biomass fuels.
After market research and comparison, the customer finally decided to choose the wood-burning heat transfer oil boiler system as the core heat source equipment.
Opportunity for Cooperation: Agent Team Promotes the Smooth Start of Project.
The success of this project can not be separated from the active promotion of the local agent team in Bangladesh. The project was jointly promoted by the Bangladesh agent and the client agent.
In the initial stage of the project, EPCB boiler agent communicated with customers for many times, deeply understood the key factors such as customer's production demand, fuel type and equipment installation space, and fed back relevant information to EPCB technical team.
Subsequently, the EPCB engineering team closely cooperated with the agent team to conduct a comprehensive analysis of the customer's site situation, including:
Moisture content and combustion characteristics of wood fuel
Requirements of production line for thermal power and temperature stability
Equipment installation space and boiler room layout
Environmental protection emission requirements
Dust removal system configuration
After several rounds of technical exchanges and scheme optimization, the technical scheme of 3 million kcal vertical wood-burning heat transfer oil boiler was finally determined to meet the stable operation requirements of customers' production lines.
Efficient and reliable vertical wood-burning heat transfer oil boiler system
According to the special working conditions of wood processing industry, EPCB has designed a complete solution of heat transfer oil boiler system for customers.
1 Boiler main body design
The core equipment of the project is 3 million kcal vertical wood-burning heat transfer oil boiler. The vertical structure design has the following advantages:
Small floor space, suitable for boiler room layout with limited factory space.
Optimization of flue gas flow to improve heat transfer efficiency
Convenient maintenance and stable and reliable operation.
The boiler adopts efficient combustion structure and multi-return flue gas heat exchange design, which makes the fuel burn more fully and effectively improves the thermal efficiency.
2 Biomass fuel utilization
A large number of wood wastes, such as sawdust, wood blocks and scraps, are produced in the production process of customers. These materials can be used as boiler fuel after simple treatment to realize energy recycling.
Compared with traditional fossil fuels, biomass fuels have obvious advantages:
Low fuel cost
renewable energy
Reduce the cost of waste disposal
Reduce carbon emissions
This is also one of the important reasons why customers choose wood-fired heat transfer oil boilers.
3 Complete system configuration
In order to ensure the stable and efficient operation of the system, EPCB provides customers with a complete boiler system configuration, including:
A boiler body, an efficient combustion chamber, a blower, an induced draft fan, an oil separator, a high oil tank and a low oil tank, an electric control system, an oil-gas separator, an oil injection pump, an air preheater, a multi-tube dust collector, a spray dust collector, a sewage circulating pump and a complete set of installation materials;
The complete system design not only improves the boiler operation efficiency, but also ensures the long-term stable operation of the equipment.
Environmental Protection Design: High-efficiency Dust Removal System Meets Emission Requirements.
With the continuous improvement of industrial environmental protection standards, the emission control of boiler system has also become the focus of enterprises.
In this project, EPCB has configured a multi-stage dust removal system for customers:
Multi-tube dust collector
Multi-tube dust collector can effectively remove larger particle dust from flue gas through centrifugal separation principle.
Spray dust collector
After multi-tube dust removal, the flue gas enters the spray dust removal system, and fine dust particles are further removed by water mist adsorption, and the flue gas temperature is reduced.
Through this combined dust removal scheme, the system can significantly reduce the particulate emission in flue gas and meet the local environmental protection requirements.
Full Technical Support of EPCB Engineers
After the equipment manufacturing is completed, EPCB quickly organizes the delivery and arranges technicians to go to the customer factory in Bangladesh. In the equipment installation stage, EPCB engineers are stationed at the site to provide technical guidance for key links, including:
Boiler foundation construction
Boiler body installation
Pipeline system connection
Installation of heat transfer oil circulation system
Installation of dust removal system
Wiring and debugging of electric control system
Ensure that the equipment is installed according to the design standards through strict installation guidance.
In the debugging stage, the engineer conducted a comprehensive inspection and test of the system, including:
Commissioning of combustion system
Adjustment of induced draft and blast system
Heat transfer oil circulation test
Control system function test
Finally, the whole system was successfully debugged and put into operation.
Operation effect: stable heating and significant energy saving.
After the equipment is put into operation, the whole heat transfer oil boiler system runs stably, showing good overall performance and energy utilization efficiency. The boiler can continuously and stably output high-temperature heat transfer oil, which provides reliable heat energy guarantee for the wood processing production line, so that wood drying, hot pressing and related processes can maintain continuous and stable operation, thus effectively avoiding the influence of heat source fluctuation on production efficiency.
At the same time, by optimizing the design of combustion structure and the application of efficient flue gas heat exchange system, the boiler can fully release the fuel calorific value and improve the heat utilization rate, so that the overall thermal efficiency of the equipment can be maintained at a high level, and the fuel consumption can be significantly reduced while ensuring stable heating. Because a large amount of sawdust, wood blocks and scraps produced in the production process of enterprises can be used as boiler fuel, customers not only realize the resource utilization of waste materials, but also greatly reduce the procurement cost of traditional energy, thus effectively reducing the overall energy expenditure of enterprises.
In addition, the multi-stage dust removal devices supporting the boiler system, including multi-tube dust collector and spray dust collector, greatly reduce the dust particle emission in the flue gas by combining graded filtration with wet adsorption, ensure that the emission index meets the local environmental protection requirements, and realize the high-efficiency energy utilization while taking into account the green environmental protection production goal.
