Advanced equipment for Desulfurization and Dust removal of Steam Boiler and its principle Analysis

The exhaust dust concentration of various combustion structures in small and medium-sized boilers is far higher than the maximum allowable smoke concentration specified in domestic standards. Therefore, in addition to correctly selecting the combustion structure and improving the operating level, Coal-fired boilers must also be equipped with dust removal equipment at the rear of the boiler, and dust particles in the flue gas must be collected and then discharged into the atmosphere.

That the purchase of a natural gas boilers How much is it? Xiao Bian asked this reason our technical staff has many years of experience in the boiler, he gives a lot of factors that affect the price of the boiler, a look at it!

According to our learned Wenzhou Municipal People's Government on February 12 issued a notice "Wenzhou Blue Sky win the Battle of action to implement the program (draft)", the details are as follows.

Accelerate the implementation of the relevant arrangements for the deployment of national, provincial and develop natural gas and other clean energy. According to Yi gas of the gas, the electric power should be the principle, and actively guide enterprises to implement energy clean energy alternative, 2020, the basic completion of provincial trunk pipeline construction, the basic realization of natural gas every county, to further improve the urban and rural distribution pipe network construction , the city's natural gas consumption reached 570 million cubic meters, the proportion of non-fossil fuels in total energy consumption to reach the provincial requirements. Orderly development of hydropower, safe and efficient development of nuclear power, optimizing wind energy, solar energy development layout, local conditions to develop biomass energy, geothermal energy and so on. Where the conditions of availability of resources, to encourage the development of county biomass cogeneration, biomass briquette boilers and biogas. Orderly development of natural gas peaking power plants and other interruptible user, in principle, to new natural gas cogeneration and gas chemical projects. Continue to implement the priority generation and purchase of electricity system to ensure the city's renewable energy generation full protection of the acquisition.

Strict new coal project access, the implementation of the reduction of coal instead. According to the State to win the Battle of the sky three-year action plan calls for no new 35 steam tons / hour high-polluting fuel boilers. By 2020, the city's coal accounts for the proportion of total energy consumption fell to 42.8% or less, the city's total coal consumption decreased by 5% compared with 2015. According to focus on the use of coal and clean use of principles, focusing on reduction of non-coal for electricity, increase the proportion of electricity from coal in 2020, the city's electricity and central heating coal proportion of total coal consumption reached provincial requirements. Continue to promote alternative energy coal and oil, replace reached the provincial requirements.

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. Strict control of new coal-fired units installed capacity in the region rely on new clean energy generation and transmission to meet outside the main electricity consumption. In the premise of protecting the power system security and stable operation of 2020, to accept the outgoing power levels to at least 38%.

Consolidate construction achievements combustion zone ban, increase efforts to eliminate small coal-fired boilers. According to the National to win the Battle of the sky three-year action plan calls for phasing out the 10 steam tons / hour and coal-fired boilers, the county level and above urban area basically out of coal-fired tea furnace, operating a stove, grain storage and drying equipment, etc. facilities; basically eliminated the city's 10 steam tons / hour and 35 steam tons / hour of coal-fired boilers; 35 steam tons / hour and more polluting fuels and energy-efficient boilers to complete the transformation of ultra-low emissions; low nitrogen gas boiler basically completed the transformation; city built-up area of ​​biomass boilers implement ultra-low emissions transformation.

Principle gas boiler gas boiler can be divided according to the fuel gas boiler, boiler city gas, coke oven gas boiler, liquefied petroleum gas boiler and boiler; functions can be divided in accordance with KS-Q water gas boiler, CLHS / CWNS gas water boiler (including gas heating boiler and bath gas boiler), LHS / WNS gas 11 mw rice husk fired steam boiler in indonesia and the like; can be divided according to the structure of vertical gas boiler, gas boiler horizontal; in accordance with the flue gas flow can be divided into three single backhaul backhaul gas boilers and gas boiler.
