Benefit analysis of 15 MW biomass direct-fired power cogeneration project

Abstract Biomass direct-fired power generation technology has many advantages in realizing large-scale harmless utilization of biomass resources. It is an effective way to achieve the goal of carbon peak and carbon neutrality. Taking the 15MW direct-fired biomass power generation project of typical unit configuration as an example, this paper constructs a CHP system with biomass as fuel to replace the traditional coal-fired boiler for power generation, analyzes its economic, environmental and energy-saving benefits. As shown by results, compared with the conventional coal-fired power plant, the system cannot only save more than 700000 tons of coal, but also reduce more than 1610.41 tons of carbon dioxide emission, more than 26.41 tons of sulfur dioxide emission and more than 3000 tons of smoke and dust every year. The adoption of a new boiler and straw thermal power technology can competently deal with the three major problems of energy use, environmental protection and farmer’s income increment, which is of great significance to realize the effective cycle of “resource product renewable resource” economy.
