March 19, 2019, Tangshan, Hebei Province, the city government official held "2019 Tangshan depth control key industries scientific and technological achievements Matchmaking" meeting the cement industry on air pollution emissions caps mobilization discussion. According to the news conference, Tangshan City Cement companies need before the end of September this year will be dust, sulfur dioxide, nitrogen oxides are controlled to not more than 10mg / m³, 30mg / m³, 50mg / m³. Official documents will be introduced in the near future.
It is reported, as early as in September last year, Tangshan cement industry in particular has a value of air pollutants emissions of nitrogen oxides emission concentration is less than 50mg / m³ proposed.
September 3, 2018, Tangshan Municipal Government issued the "ecological environment in Tangshan depth remediation tackling month action plan", "plan" industrial enterprises in pollution control, discharge of pollutants in the cement industry to make the following requirements: single production of raw grinding material, bag filter employed; one mill kiln production process, humidification tower may be used - electric precipitator dust collection system, dust emission concentration ≤10mg / m³. Rotary kilns for cement kiln and, preferably high dust coating, conditioning tower may be used - electric precipitator, dust emission concentration ≤10mg / m3, the concentration of sulfur dioxide emissions ≤50mg / m3, nitrogen oxides emission concentration ≤ 50mg / m3.
The advantages of horizontal resolution horizontal gas full automatic steam boiler steam boiler gas with a higher degree of automation world automatic burner as the primary combustion equipment. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. Burner combustion process is controlled by a controller of a more advanced combustion process. The present invention may be implemented fuel boiler functions required for normal combustion, and in a normal state, the automatic stop accident protection state and the abnormal situation, and equipped with a temperature controller and a respective proportional pressure regulator, high low temperature indication , indicating overpressure is adjusted. Level 1 to ensure that the water level fluctuation within the normal range, supporting equipment, advanced comprehensive technical performance. 2. The water circulation simple, rational structure compression member, to ensure safe operation under the conditions of the water quality. 3. The overall structure is reasonable, compact, fast loading and qualified factory. This product manufactured consists of three parts: the host, chimney and duct system of a boiler, wherein the host and manufactured by the factory chimneys, pipelines and valves and the host supporting instrumentation free installation, and the stack may be assembled on-site host. It may be on-site air source, power supply, water connection is detected. Installation cycles are significantly reduced. 4. Advanced design performance. Boilers host belongs to the whole structure. Burner mounted on the front cover of smoke, the main body is provided with a heating surface and the combustion chamber. The present invention has a reasonable structure, compact, low consumption of steel, biasing bellows tank furnace, using new lightweight thermal insulation material, packaging using a color sheet, a rectangular parallelepiped packaging advantages boiler performance, weight, frame size and appearance are much better than the domestic capacity products. Boiler feed water device is provided on the right side of the base boiler boiler, combining it with the host, you do not need a further base.
Classification and distinction and design a gas boiler, gas boiler gas boiler classified in accordance with the fuel can be divided into natural gas boilers, boiler city gas, coke oven gas boiler, liquefied petroleum gas boilers and gas boilers; according to the function can be divided into gas boiler water , gas hot water boiler (gas heating boiler comprising a boiler and bath gas), gas full automatic steam boiler and the like; can be divided according to the structure of vertical gas boiler, gas boiler horizontal; in accordance with the process can be divided into a single flue gas boiler and tris backhaul backhaul gas-fired boiler. Second, the difference between fuel oil-fired boiler fuel boilers and gas boilers is fuel (such as diesel, oil, kerosene, etc.), fuel gas-fired boiler to gas (such as natural gas, city gas, biogas as well as liquefied petroleum gas, etc.), depending on the boiler What fuel burning device called a burner, boiler gas burner configuration called gas-fired boiler, oil boiler burner configuration called oil-fired boiler, oil-fired boiler and gas boiler difference is that what fuel burners. Third, the design of the boiler furnace by the gas boiler structural design pressure, provided through the top of the large pores, the boiler operates at atmospheric pressure, away from the danger of explosion; boiler furnace using computer simulation to optimize the design, the size of the boiler is fully optimized, so that coordination and beautiful form. Vertical-mounted boiler combustion at the burner, combustion of the fuel within the positive pressure furnace, baffle interposed smoke tube, slow smoke evacuation rate, to strengthen the heat exchanger, the heat furnace to ensure maximize fuel combustion water, improving the thermal efficiency of the boiler; horizontal wet back boiler full three pass structure, the length of the flue gas flow, reducing exhaust gas temperature, the whole corrugated furnace provided, so that the flame produced a strong turbulence to improve the heat transfer coefficient strength, and effectively It is prevented due to thermal expansion and contraction of metal results in a reduction of the life of the device; smoke tubes of large diameter and large pore bridge the gap, the boiler at equal time scale coating thin and easy to clean.
1. Boiler thermal efficiency test: a) determination of boiler evaporation; b) boiler excess air coefficient detection; c) exhaust smoke temperature detection; d) fuel combustion efficiency test; e) boiler thermal efficiency test; f) fuel consumption; g) Steam to coal ratio.
2. Boiler new product stereotyped energy efficiency test: Determine whether the boiler thermal performance indicators are consistent with the design and determine the operation mode of the equipment. Such as boiler evaporation, boiler thermal efficiency, combustion efficiency, various heat losses and so on.
3. Boiler operation adjustment test: Determine the most economical operation mode of the boiler and identify defects in the boiler operation. Such as boiler maximum load, boiler minimum load, fuel requirements, economic load, reasonable exhaust gas temperature, optimum wind coal ratio, excess air ratio, secondary air ratio and so on.
4. Comparative test of thermal performance before and after boiler reform: changes in evaporation, effects of combustion, thermal efficiency of boilers, etc.
5, fuel industry analysis, elemental analysis: to judge the quality of oil, gas and other fuels, easy for enterprises to control the quality of fuel into the plant.
6, water quality testing, scale analysis: determine the quality of water, control the boiler water indicators to prevent boiler fouling.Free Chat
