Use biomass gasification to convert biomass into flammable gas, then burn the biomass gas to produce hot water, steam or thermal oil.
The boiler will lose some water due to sampling, waste water discharge, leakage, etc. during operation, and the production return water is contaminated and cannot be recycled, or there is no vapor return water, water that meets the water quality requirements must be restocked. Make-up water is that portion of the boiler feed water that is supplemented by a certain amount of production recovery. Since boiler feed water meets certain quality requirements, make-up water generally must be properly treated. When the boiler does not produce return water, the make-up water is equal to the feed water.

Note:
When switched on, the water level was at the lowest visible level previously, so that as the boiler water temperature rises and steam begins to be generated, the water level in the steam drum will inevitably rise to the point where the accidental drain valve must be opened for drainage. This not only results in a loss of desalinated water, but also a loss of heat.
When the cold oven is filled with water, the temperature of the drum wall is equal to the temperature of the surrounding air. When the feed water enters the drum through the economizer, the temperature of the inner wall of the drum increases rapidly. , while the temperature of the exterior wall will increase with the heat of the interior wall. It will spread to the exterior wall and slowly increase. Since the drum wall is thicker (45 to 50 mm for a medium pressure ovenn and 90 to 100 mm for a high pressure furnace), the temperature of the outer wall increases slowly.
