To further promote the comprehensive management of coal-fired boilers, Jincheng City, Shanxi Province, according to "Jincheng Blue win the Battle of three-year action plan" requirements, plans to complete 109 units of 10-20 tons of steam "small coal-fired boilers" within this year the phase-out, at the same time, Jincheng will start working out of 35 tons of steam coal-fired boilers.

This year, Jincheng counties (cities, districts) the environmental sector will urge the relevant enterprises and institutions to eliminate the basis of 10 tons of steam and coal-fired boilers on in 2018 to accelerate the phase-out and 20 tons of steam coal-fired boilers. This year, the city to complete 109 units (10-20 tons of steam boilers) working out of a total of 589.5 tons of steam boilers; at the same time, Jincheng will also speed up the foundation and 20 tons of steam coal-fired boiler out, start 35 tons of steam phase out coal-fired boilers, in principle, within the city's new domain-wide 35 tons of steam coal-fired boilers.

In addition, Jincheng will accelerate the transformation of ultra-low emission. Before the end of September this year, the city will complete 52 units (65 tons of steam per hour and higher coal-fired boilers) coal-fired heating boilers ultra-low total of 4530 tons of steam boilers transformation, and the county (city) built-up area, biomass boilers emissions transformation. After transformation, under condition of the reference oxygen content of 6%, soot, sulfur dioxide, nitrogen oxides emission concentration of these boilers respectively not higher than 10 mg / m, 35 mg / m and 50 mg / m.

Transformation of low nitrogen in the combustion aspect, before the end of October, Jincheng station 610 will complete the transformation of low-nitrogen combustion Total 1940.15 tons of steam gas boiler, after completion of the transformation, the boiler NOx emission will not exceed 50 mg / m.

Steam boiler which automatically displays the instrument will encounter problems in accordance with the steam boiler fuel can be divided into electric steam boiler, steam boiler fuel, gas steam boiler using the water level; in accordance with the constitution can be divided into vertical steam boilers, horizontal steam boiler, small steam boiler mostly single, double the return of the vertical structure, large steam boilers and more horizontal structure of three return. There lowland water or a display apparatus using the automatic water level when the water level in steam boiler water level is only a low level of installed devices, and even water pipes are too small; the water level or a Low level using the instrument, when the steam boiler is automatically displayed only one water; a water drain device, drain cocks no ground; on a drum water level is effective, other water damage; plug screwed on the fixed level; on tap water gauge leak, leaking; water false water level on the display unit; the drum water level in the two water gauge level of inconsistency; water is often broken glass; water gauge glass without guard; a water gauge glass plate not shown in the red line indicating the water level; water gauge glass plate is dirty, the water level observation is unclear. Steam boiler water level glass observation level of inconsistency and the main reason is unclear steam boiler for long periods of time rinse in running water, a daily maintenance is not carried out, resulting in water cock rust, gas, water and even the block, or insufficient packing or aging deterioration. False water level phenomenon, in addition to gas, water or even the cock pipe is blocked, but also could be vapor, the water pipe connected to the water level due to misalignment connected; steam, water tap handle installed the wrong position resulting cock closed, since there poor water quality, the water level in the boiler and false priming. Water gauge glass is broken mainly steam, water faucet centerline not aligned, the presence of glass bending stress; long glass without expansion gap; water gauge is being cold draft at window glass, and glass pipe quality was poor. During the operation of the boiler, the water level was found is not clear, to shutdown immediately ultra-high water level, timely detection of problems.

Gas-fired boiler, fuel gas-fired boiler, fuel gas hot water boiler, steam boiler fuel: gas boiler includes a gas water boiler, gas hot water boiler, gas steam boilers, gas hot water boiler which is also known as gas heating boilers and gas boilers bath, gas as the name suggests refers to the boiler fuel for the gas boilers, gas boilers and oil-fired boiler, electric boiler for hot water only compared to the most economical, most people have opted for a gas boiler as steam, heating, boiler equipment for bathing. Gas boiler comprising KS-Q water gas boiler, CLHS (CWNS) gas hot water boiler, LHS (WNS) gas steam boiler and the like, wherein the gas comprises a gas hot water boiler heating boilers and gas boilers bath, with the state "natural gas "project implementation, gas boiler gradually become the people's choice.

Electric boiler requirements for electric boiler for hot water onlys for water main applications where large areas of hotels, restaurants, colleges, factories, etc., in its work, after a long time the surface or internal scale phenomenon occurs, this phenomenon greatly affect the equipment, the following it'll tell you about cleaning method: 1, acid cleaning method: ① this pickling solution can not only clean up the boiler scale (except when nitrates scale, add hydrofluoric acid), and very little corrosion gas hot water boiler. ② descaling pickling process using hydrochloric acid or nitric acid, most of the cleaning. Pickling solution by adding nitric acid or hydrochloric acid was added inhibitor of the corrosion inhibitor composition. 2, the mechanical descaling method: when the electric furnace with a loose boiler scale and slag, so that the cast iron hot water boiler shutdown cooling, boiler water let go of, after washing with water, can be used flat shovel, wire brushes, and a motor milling descaling header. 3, alkali cooking cleaning law: ① alkali cooking method is simple, relatively small side effects. ② alkali cooking method of cleaning descaling, pickling cleaning effect than the difference method, but since a base boiled loose scale, so it is difficult for, may be a cooking method I with a base with hydrochloric acid cleaned scale before acid pickling deal with. Scale electric boiler efficiency is an important factor in the life and influence, in order to ensure it is safe to run the economy, the need for a reasonable scale clean-up work, so essential to get rid of scale, reduce equipment failure and reduce damage.
