As compared to conventional industrial boilers, an equivalent biomass boiler needs more space in the boiler house. The reason for larger space requirement is connected to the extra fuel handling equipment and sophisticated filter system that are compulsory. A larger hopper is required to store the wood fuel, be it wood pellets or chip.
Wood pellets are preferred fuel option in China market as they are completely dry and processed. On the other side, the wood chip contains a higher amount of moisture which can cause problems. When comparing prices of wood fuel, pellets are far more expensive. While tonne of pellets cost around £130, the wood chip is worth £30 per tonne.
Installation of Industrial Biomass Boilers
The most important requirement to think about when installing an industrial boiler is the space for the fuel storage, water tank and the boiler itself. Unlike smaller domestic boilers, industrial biomass boilers can drastically vary in the size depending on the heating system, building heating requirements and storage space. Oversized boilers lead not just to higher costs but also to waste of energy over its lifespan.
The process of installation depends on the current heating system and in some cases may involve integration with your current heating system instead of complete system replacement.
How an industrial biomass boiler works?
The heart of an industrial biomass boiler system is a hot water or steam boiler that operates with a particular type of fuel. In case of biomass boilers, this fuel includes different types of wood, such as pellets, chip or logs. The boiler heats up the water inside it, which is then transmitted to the consumers via pipe systems. The cooled water or the condensed steam returns to the boiler where it is heated again. Loss of water must be compensated by treated fresh water to avoid corrosion.
