There are four primary classes of biomass fired boiler for power systems: direct-fired, co-fired, gasification, and modular systems. Most of today's biomass power plants are direct-fired systems that are similar to most fossil-fuel fired power plants. The biomass fuel is burned in a boiler to produce high-pressure steam. This steam is introduced into a steam turbine, where it flows over a series of aerodynamic turbine blades, causing the turbine to rotate. The turbine is connected to an electric generator, so as the steam flow causes the turbine to rotate, the electric generator turns and electricity is produced. Biomass power boilers are typically in the 20-50 MW range, compared to coal-fired plants in the 100-1500 MW range. The small capacity plants tend to be lower in efficiency because of economic trade-offs; efficiency-enhancing equipment cannot pay for itself in small plants. Although techniques exist to push biomass steam generation efficiency over 40%, actual plant efficiency are often in the low 20% range.
Our environmental management efforts continue to increase, located in Wuhai City of Inner Mongolia is also actively respond to national policies, by removing, shutting down non-compliance of the measures within the jurisdiction of coal-fired boilers, etc., to improve air quality within the city.
Recently, a reporter to follow the staff Haibo Bay Area environmental monitoring brigade, examined the case of shutting down coal-fired boilers in rural areas. Trinidad town in Wuhai unity Village, coal-fired boiler is the main source of heat in the village residents, schools, hospitals in the town and airport, but because they do not meet environmental requirements, the boiler has been officially shut down at the end of 2018. Haibo Bay Area Environmental Protection Agency environmental monitoring battalion to us to: "Removing the boiler is 20 tons of steam coal-fired boilers, each heating season about to burn more than 3,000 tons of coal in accordance with the municipal government requirements. within the deadline 20 tons of steam boilers to be all removed, replaced with clean energy. since November 2018, this block of sea area has access to a central heating all children. "
So far in 2013, Wuhai City in strict accordance with regulatory requirements grid, earnestly implement the responsibility of inspectors on-site supervision, and has eliminated 20 tons of steam coal-fired boilers for heating and tea bath furnace 791 units, of which 2018 out of 58 units. Meanwhile, municipal and district environmental protection departments at all levels to increase on-site law enforcement and ensure that the boiler is no longer out of the resurgence. Up to now, it has no built-up area of Wuhai City and 35 tons of steam coal-fired boilers to achieve a stable discharge standards.
