The ash deposition mechanism in boilers burning Zhundong coal with high contents of sodium and calcium: A study from ash evaporating to condensing By Xuebin Wang, Zhaoxia Xu, Bo Wei, Lan Zhang, Houzhang Tan, Tao Yang, Hrvoje Mikulčić and Neven DuićGet Price
Biomass power systems are typically below 50 MW in size, compared to coal-fired plants, which are in the 100- to 1,000-MW range. Most of today's biomass power plants are . direct-fired systems. The biomass fuel is burned in a boiler to produce high-pressure steam that is used to power a steam turbine-driven power generator.Get Price
