Method for burning biomass as the primary fuel in the boiler thermal electricity generating unit with a capacity of 50 MW

摘要

method of combustion of biomass as fuel, the basic boiler thermal generation unit electricity capacity to 50 mw, is designed for energy users outside the network elektrociepu0142ownictwa professional.is characterized by the fact that much fragmented and dried biomass concentrations from 2 kg / m3 to 10 kg / m3 is in deficiency cold air to the lower part of the cyklonowej angles (k1) paleniskowej chamber (k) the boiler heat, with a speed of 17 m / sec to 30 m / sec.of biomass and air are directed in parallel alternately to the horizontal axis and vertical axis cross-section of the chamber paleniskowej (k) and deflected from the vertical walls of the lower part of the cyklonowej (ki) paleniskowej chamber (k) of boiler heat angle beta from 0o to 15o at 1.5 - 1.8 times higher than the melting temperature of ash spalanej biomass.here after smoking it in the morning, around 80% of biomass ash particles from biomass after transition in liquid phase are discharged outside, and approximately 20% of volatile combustible fraction is transported to the upper part dopalaju0105cej (k2) paleniskowej chamber (k) by the reduction of area (p).
