qualified coal fired dzl boiler
To proceed from reality, should be in accordance with the electric power, gas should the gas, the coal should be coal, should be hot the thermal principle, promote the use of all kinds of clean energy for winter heating cleaning. In order to reduce air pollution and protect people's warm winter as a foothold to enterprises, government promotion, residents can withstand the principle of gas after the first change to gas will change in gas assurance, the price is acceptable on the basis of sound promote the "coal to gas" and central heating engineering, in district heating supply pipe network can not cover, vigorously implement the replacement of coal-fired power heating project.
Good job of marketing system storage capacity for natural gas. Accelerate the construction of natural gas transmission and distribution network, the new natural gas volume priority for life and severe winter areas of urban air pollution and coal for heating alternative. In principle, to new natural gas cogeneration and gas chemical projects.
Accelerate agricultural and pastoral areas "coal to electricity," the process of upgrading the power grid. Coordinate development of power transmission project construction, etc. are encouraged to promote the regenerative electric heating. Around on the "coal to electricity" project supporting grid should be given support, coordination "of coal to electricity," "coal to gas" land for construction.
In accordance with national requirements, shutting down environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance. For shutting down the unit's capacity, coal consumption and emissions targets, allowed to trade or replacement, can co-ordinate arrangements for building the capacity of ultra-low emission coal-fired units.
According to air quality improvement requirements to accelerate the delineation of high-pollution fuel combustion zone ban and to expand the scope of, and actively promote the elimination of small coal-fired boilers. The county level and above urban area basically eliminated 10 tons of steam per hour and coal-fired boilers and tea furnace, stove and other operating coal-fired facilities, in principle, to 35 tons of steam per hour, the new coal-fired boilers, in principle, other areas on no new 10 tons of steam per hour of coal-fired boilers. While banned out of coal-fired boilers, pressure boilers market regulators cancellation of registration certificate to use.
Through estimation: If the exhaust gas temperature of 150 ℃, when the excess air ratio from 1.5 to 3.0 cases, the combustion is generally bituminous coal, anthracite qualified coal fired dzl boilers, heat losses from about 5% to 10%, reducing the thermal efficiency of the boiler nearly 5 percentage points. While the chain grate boiler excess air ratio was mainly due to leakage caused by the grate, but also accounted for a large proportion of the furnace leakage, strict plugging wind, to improve boiler thermal efficiency, reduce coal consumption, save energy resources it is very significant. Before plugging the wind, the first thing leakage test boiler.
Treatment of natural gas leakage in horizontal gas qualified coal fired dzl boiler room
According to relevant data, with the speeding up of changing coal to gas, the project that change industrial coal-fired boilers to industrial gas boiler no matter in quality or quantity are growing faster. In addition to the support of national policy, the development of industrial gas boiler also benefited from the convenience of natural gas.
There are a number of options available for the direct co-firing of solid biomass materials in large pulverised coal fired qualified coal fired dzl boilers, including: pre-mixing the biomass with the coal, added dedicated biomass mills, 100% conversion of one existing mill, parallel boilers, and gasification.
