Description

Technical Field

[0002] Biomass steam generator is a steam generator that uses biomass pellets as fuel. Biomass pellets, also known as artificial coal, are pellet fuels made from waste crops such as straw, rice straw, wood, sawdust, peanut shells, melon seed shells, bark, etc., through crushing, mixing, extrusion, drying and other processes. The working principle of the biomass steam generator is to put biomass pellets into the equipment for combustion, generating high-temperature and high-pressure flue gas. The flue gas enters the water pipe area through the furnace and flue, heating the water in the water pipe. The heated water becomes steam and is discharged from the equipment through the exhaust pipe. Since the biomass steam generator is a loop system, the steam will be cooled and condensed after use, turning into water and returning to the pipe for reheating and recycling.
