1, high thermal efficiency, cheaper fuel
The need for the country to promote low nitrogen differentiate the steam produced by fire-tube boiler and water tube boiler What? Issued from the national emission reduction policies and monitoring efforts, the state vigorously promote low nitrogen determination boiler unabated. Reduce NOx emissions is to improve the ambient air quality monitoring data needs in recent years shows that the typical features of a larger pollutant PM2.5 exceeded the proportion of long seriously overweight and regional situation, to improve ambient air quality is facing enormous challenges. Domestic and international research and management experience shows that regional PM2.5 pollution control is a very difficult system engineering, must be analyzed on a consolidated basis, we propose targeted control measures in order to effectively alleviate the region PM2.5 pollution. PM2.5 including primary and a secondary discharge section two generating particles, Beijing, for example, a high proportion of secondary particles, particularly PM2.5 weight ratio of the secondary particle contamination significantly increase over regular time periods. There are observations indicate heavy contamination with environmental changes PM2.5 NOx concentration exhibits a strong correlation, characterized in that changes in synchronization. NOx is an important precursor PM2.5, two roles in the formation process: First, the reaction of chemical components NO3- are important secondary particles; photolysis through two chain reaction O3-, increased an oxidizing atmosphere, providing SOx, NOx oxidation NO3- and SO42- oxidant. California CAMQ use simulation models to cut NOx emissions once the impact of PM2.5, the result is every tonne of NOx emissions can be reduced by about 0.13 tons PM2.5.
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 differentiate the steam produced by fire-tube boiler and water tube 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.
Electric steam differentiate the steam produced by fire-tube boiler and water tube boiler into electronic and mechanical two categories: electric boiler level controller is a central nervous system-controlled steam, into mechanical and electronic two categories. Electronic probe electrode level controllers by three different high and low control level (i.e., the difference in height level) so as to control the heating time of the water supply pump and the furnace heating system, working pressure is stable, broad range of applications .
