Turn Loss into Win|How does Rubber wood production line use Boiler to Counterattack Successfully?

April 12, 2022

Rubber wood is the main trunk of the rubber tree. After the rubber tree grows, the rubber is tapped every year, and the sap that flows out is the raw rubber, which is the raw material for making rubber. Generally, the production period of rubber wood is within 20 years. After more than 20 years, the rubber production will be greatly reduced. When the main trunk of the rubber tree no longer produces glue, it can be used for furniture production.


The diameter of rubber wood is 15-1000px. The wood is soft and prone to moths. If it is used in furniture production, it needs to be dried to make the wood not easily deformed and free from moths.


In Thailand, there is a furniture factory that produces rubber wood. Every year, a large amount of rubber wood is used for furniture production. Due to poor production management, the factory cannot make ends meet. Coincidentally, EPCB company inspected the rubber wood production line in Thailand, and the head of the factory invited EPCB engineers to visit and guide.


In the factory, EPCB engineers found that the boilers used for drying wood on the production line were coal-fired boilers, which were expensive, and the bark and other wastes generated in the wood production process were disposed of at a low price to the plywood factory. This invisibly increases a lot of running costs.


The engineers of EPCB made suggestions to the factory and designed a boiler for the rubber wood factory to digest the bark waste in the production, and no longer use coal as a heat source to dry the wood.


EPCB boiler design is as follows:


1. Dedicated waste wood-fired boilers, 6t steam/hour boilers use manual feeding, and waste wood boilers above 6t steam/hours use crushers and combined belts to transfer them into the boilers.


2. For steam drying, steam pipes are used to directly enter the drying room. The drying rooms are arranged side by side. The waste heat from the drying material room is advanced to the new drying room, and the new material is preheated first to save fuel.


3. To burn waste wood (bark), use flue gas pre-drying, and use the drying area to achieve.


4. For flue gas emission, cyclone dust removal is used for preliminary dust removal. After dust removal, EPCB invention patent is added, and wood spark fire-compensating flame retardant enters the bag dust removal system. The flue gas emission meets the emission requirements and realizes pollution-free emission.


Since adopting this new design system, the production cost of the rubberwood factory has been reduced by more than 10%, and the floor space of the factory waste wood has also been reduced by more than 70%. The business has gotten better and better, and within five years, the customer has quickly replicated seven new plants using such systems.
