Due to the rapid development of social economy and the improvement of the awareness of energy conservation and environmental protection, the environmental damage caused by industrial coal-fired boilers has become increasingly apparent, especially the serious smog pollution in recent years. Therefore, everyone pays more and more attention to clean energy- biomass. So, can coal-fired boilers be directly converted to biomass boiler?
The answer is no for these reasons:
1. Common biomass fuels include wood chips, wood chips, rice husks, palm shells, corncobs, etc. Due to the different sizes of biomass from coal, biomass boilers require larger feed hopper than coal-fired boilers to prevent feed jams.
2. Biomass is easier to burn than coal, and usually starts to burn when it enters into the furnace; while coal is relatively difficult to ignite and burns slowly. Both fuels have different requirements for the size of the furnace and the design of the furnace walls. If the coal-fired boiler is directly converted to fire biomass, the furnace wall will be damaged.
3. Biomass is flammable, consumes oxygen faster, and needs to replenish air in time, so the biomass boiler has secondary air to supplement the air distribution, and needs to be equipped with a soot blower to prevent dust accumulation, which will affect the service life of the boiler.
ZOZEN SZL series biomass-fired boilers have a reasonable design. Compared with traditional coal-fired boilers, SZL series boiler has a higher furnace, which is better for full combustion of biomass fuels; the inclination angle of the front furnace arch is increased to prevent the burnout of the furnace.
Due to the good design and adjustment, the thermal efficiency of SZL biomass fired boiler is as high as 88%. Welcome to consult for more details.
