There are many heat sources, including biomass pellet, waste wood, natural gas, electric energy, boiler steam and so on. At present, the heat source of the wood sawdust rotary drum dryer on the market is usually waste wood or biomass pellet.

The advantage of using waste wood or biomass pellet as heat source is low drying cost, simple operation, and not easy to catch fire. Therefore, when the customer orders the wood sawdust rotary drum dryer, he will choose to order the hot blast stove together or choose to make the hot blast stove at the production site of the sawdust dryer.
If the heat source of the wood sawdust rotary drum dryer uses waste wood or biomass pellet, the bottom of the hot blast stove should be added in the process of production to prevent the fuel from falling, which is also easy to clean up the ash of the fuel.
There are two factors affecting the fuel consumed in the drying process of the wood sawdust rotary drum dryer, First: the evaporation amount of the wood sawdust rotary drum dryer (the heat required for 1kg of water evaporation is fixed, so the evaporation amount of the wood sawdust rotary drum dryer must be clear) . Second: the heat value of the heat source. (For example, when biomass pellet machine is used as a heat source, 3800-4200kcal per kilogram of biomass pellet machine).
