Since gas steam boiler 4.2mw energy saving fashion choice to create a new concept of reform and opening up, China's industry has developed rapidly, public life is getting better. However, in recent years, a large number of industrial emissions, vehicle exhaust and dust blowing sand caused by environmental pollution, making the environmental quality of our cities is getting worse atmosphere. Haze over the city often locked to people's survival has brought great health threat. Currently environmental governance has become central to the question from the local environmental protection departments at all levels focus on concentrating on. Gas-fired steam boilers to treatment of industrial waste gas emissions need to start from the source to replace coal-fired boilers with energy saving gas boiler, is the most effective way to quickly and directly to fundamentally solve the industrial waste gas emissions. Now, many previously used coal-fired boilers companies will need to order a gas boiler upgrade. In response to this production and sales of new gas-fired boiler situation, recently, the reporter came to Anyang, Henan Xin Boiler Co., Ltd. interviewed understand. Originally, Anyang, Henan Xin Boiler Co., Ltd. is the designated national production of boilers and pressure vessels manufacturing enterprises, boiler over forty years and one, two, three types of pressure vessel manufacturing history. It has Class A boiler production licenses and one, two, three types of pressure vessel design, manufacturing license qualification. Over the years, Yu Xin Boiler Co., Ltd. has always adhere to the quality of survival, technology and development, people-oriented business philosophy, with strong personnel and development strength, advanced technology and equipment, the production of boilers and pressure vessels products sold at home and abroad . At present, environmental pollution, improve air quality without delay. Yu Xin Boiler Co., Ltd. According to this new market demand, rapid response, and actively carry out R & D and innovation, the first time introduced a variety of specifications for the various manufacturers of gas boilers and a number of other categories of environment-friendly boiler. Gas boiler Boiler Co., Ltd. of Henan Xin has been introduced, has been widely acclaimed by various production companies, customers continue to visit, orders soared. For continued strong sales of energy saving Yu Xin gas boiler, the reporter also made a key understanding. Compared with other boiler, gas boiler, Henan Xin is wet back, waveform furnace structure, heating surface are arranged symmetrically, so that the boiler and the expansion force more reasonable; rational heated area and ensures good water circulation and heat exchange the effect of heat transfer at their best to improve the thermal efficiency of the boiler. Full butt weld wet back structure Henan Xin gas steam boiler, to avoid damage to the back wall of the high temperature flue gas, but also to ensure reliable operation of the boiler; a waveform combustion furnace, effectively reducing the thermal stress of the boiler, improved boiler safety and service life; selection of well-known international brand burners and advanced automatic control system for the boiler combustion more stable, more convenient, more secure and reliable. After Zhefan understood that reporters understand that it is one of the current fashion of choice in the situation of energy saving Yu Xin gas boiler.
Why boiler 4.2mw pressure tank, and the role of large-scale boilers to use compressed air: the boiler, in the following learning process, in the form of questions and answers will be used to carry out, because that is what we all hope for, so the site can familiarity product on deepened, and at the same time, to increase the expertise in this area. Therefore, I hope that we can be taken seriously and carried out so as to have good results, in order to firmly grasp the knowledge and correct application, thus, make their own benefit. 1. boiler feed water, which is part of the water power plant it? Boiler feed water, which is part of the power plant of the water, so on this issue, that the answer is yes. Further, in the plant, will generally focus on the water plant is provided, i.e. of the water plant for the production of desalinated water for replenishing the boiler, the boiler so that the normal operation and use.
For the 2018-2019 autumn-winter air pollution prevention and control work, Jinhua City, Zhejiang Province issued a public draft, mainly in the autumn and winter to reduce heavy pollution weather Development frequency.
Take measures to reduce coal comprehensive, non-electric focused on reducing the total coal consumption, in 2018 the city's total coal consumption reduction of 1% compared with 2015. New non-owned coal-fired units, the implementation of new large-scale coal-fired units and coal consumption of the same amount of capacity reduction or substitution, elimination of energy consumption, water consumption, environmental protection and safety is not up to 300,000 kilowatts coal-fired units. Development of industrial parks "One District One heat source" action plan, and more than 300,000 kilowatts coal-fired units were heating transformation, promote backward and shutting down small coal-fired thermoelectric integration of coal-fired boilers in the range of 15 km radius of the heat. Optimize the use of natural gas structure, in principle, to new natural gas cogeneration and gas chemical projects, to the new "coal to gas" projects, should adhere to increase coal gas reduction synchronized to gas will change, the premise of the gas supply contract signed and orderly implementation.
Coal-fired boiler (with tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities) carried out an intensive investigation to ensure that no dead ends, no blind spot. Investigation and the coal-fired boilers to register one by one.
According to the law to increase the city's efforts to phase out coal-fired boilers in accordance with regulations. Before the end of December 2018, the city basically out of 10 tons of steam per hour of coal-fired boiler, built-up areas out of 35 tons of steam per hour coal-fired boilers. Complete 1 set (Yiwu) per hour, 40 tons of steam coal-fired boilers transformation of ultra-low emissions, coal-fired plants to achieve ultra-low emission levels.
In principle, the boiler NOx emission is not higher than 50 mg / m, and comply with appropriate safety boiler specification. New installation and reconstruction of gas-fired simultaneously supporting the low NOx combustion device.
Biomass boilers to carry out a comprehensive investigation, complete control of boiler scale, distribution, fuel, furnace, pollution control facilities and pollutant emissions, and establish a list of management accounting. Yan Gesheng biomass boiler registration, strictly control the new urban area of biomass boilers. Biomass boilers should be dedicated boiler, coal and other prohibited blended with other fuels, efficient dust bags and other ancillary facilities. Actively promote the urban area of biomass boilers ultra-low emissions transformation. For existing biomass boilers, environmental inspection carried out one by one, there are multiple distributed biomass boilers, the implementation of the demolition of small and large industrial agglomeration area.
Forced circulation boiler 4.2mw water or steam only in the difference in density between water and steam as the driving force, and requires a certain power to the pump is circulated in the heating duct. Forced circulation oven due to the good water circulation, speed requirements of Sheung Shui is very low; the working pressure is generally more large, high boiler tube material and wall requirements. Forced circulation boiler drum is no longer necessary, you can have the drum, the drum can not; but for a higher pump head requirements, power consumption is greater. When the pump stops running, the pot of water flow is stopped, the need for a reliable way to prevent moisture pot of water hammer.
