Environmental situation is not optimistic that China has issued a number of environmental policy, the full range of safeguards ecological environment. Provinces are also actively to improve environmental protection, recently, Ningxia Hui Autonomous Region winter heating what is a boiler furnace pressure quora proposed implementation. details as follows.
"Clean heating embodiment of Ningxia Hui Autonomous Region (2018 Year - 2021)," recently released, "plan" put forward, Ningxia heating the status quo, to develop clean heating, the use of clean energy alternative to coal and dispersed living coal, reducing coal consumption and soot emissions, improve environmental quality in urban and rural atmosphere.
By the end of 2017, Ningxia urban and rural housing construction for heating a total area of 380 million square meters, of which the city building heating area of about 240 million square meters, rural buildings for heating an area of about 140 million square meters. Clean heating total area of about 180 million square meters, accounting for about 47% of the region's total heating area. Among them, prefecture-level city clean heating an area of about 120 million square meters, clean heating rate of about 75%; counties (cities, districts) Clean heating an area of about 50 million square meters, clean heating rate of about 62%; rural clean heating area of about 14.72 million square, clean heating rate of about 10%.
After the "plan" put forward, Ningxia, according to the "central heating mainly to the substitution of gas for coal as the first, supplemented by electricity instead of coal," the idea, according to local conditions, scientific planning, coordination implementation. City, county (district) the main city clean coal-fired co-generation, large-scale energy saving boiler central heating heat source as the basis for strengthening efforts to shut down within a small range of central heating boilers of coal. Promote cogeneration units and ultra-low emissions transformation of large boilers, improving the environmental standards.
In urban and rural interface and rural areas, in accordance with the principles of the easier issues first, and start cleaning centralized heating schools, kindergartens, hospitals and other public buildings start to play an exemplary role. The conditions of the area to promote gas boiler; encourage nearby collected plant biomass feedstock, biomass briquette forming process instead of bulk coal; encourage livestock waste, straw and other raw material for the biogas fermentation and purified, for clean heating; actively promote the development of geothermal resources as a centralized or decentralized heating heat source; support for residents to install solar hot water, electric heating equipment, such as housing, agriculture greenhouses, farms; do not have clean heating conditions actively implement clean coal alternative bulk coal.
"Plan" clearly, Ningxia will accelerate cogeneration, waste heat utilization, the cell set into a piece of construction heating boilers, focusing on the completion of the Western Xia thermoelectric (two) central heating, in Nanjing Tianyuan thermoelectric, Helan back pressure Heating Unit central heating and other projects, the completion of thermoelectric Zhongwei, Wuzhong thermoelectric, thermoelectric Dawukou LIUPANSHAN thermoelectric renovation project, to further expand the central heating area. City, county (district) heating should vigorously promote the "coal to gas," "coal to electricity", according to local conditions the development of renewable energy for heating, a pair of old, energy-saving secondary pipe network, heating network system to enhance efficiency.
Ningxia will be fully phased out small coal-fired boilers, coal-fired boiler to deepen the comprehensive compliance management, municipalities, county (district) urban area out of 20 tons of steam / hour coal-fired boilers. Yinchuan City urban area to total phase-out project cogeneration district heating pipe network covering all coal-fired heating boilers in the region. It does not have the "coal to gas," "coal to electricity" conditions in rural areas, to achieve clean coal production and warehouse distribution center full coverage, full implementation of clean coal alternative bulk coal.
Ningxia Hui Autonomous Region in the 2018-2021 four-year, with the full complement of winter heating boiler, will replace all cleaner energy boiler coal-fired boiler, to protect people's health.
Low nitrogen transformation technology transformation technology low nitrogen gas steam what is a boiler furnace pressure quora steam boiler gas analysis analysis? Currently, in order to comply with national and local environmental trend adjustment policy, the pharmaceutical industry began the boiler has been transformed, and low nitrogen transformation technology is one of them. As the current in the pharmaceutical industry, gas powered steam boiler is more extensive, Xiao Bian below to low nitrogen gas transformation gas steam boiler, for example, to analyze the technical transformation of low nitrogen gas steam boiler. Generally speaking, the low nitrogen transformation to achieve the effect is nothing more than two, one energy saving, emission reduction Second, with regard to energy-saving technologies, currently more common is the FGR flue gas recirculation technology, condensing technology, premix technology , organic combination of these techniques, the heat released by combustion of boiler fuel effectively used to enhance the operating efficiency of the boiler heat to some extent, to achieve the effect of energy saving; the reduction is divided into two general gas boiler emissions in the basic 150mg / m3 and above, and now the state is required standards 80mg / m3, or even 30mg / m3 and below, so for this standard, the transformation of emission reduction First, instead 80mg / m3 emissions, and second, is 30mg / m3 emissions, according to the specific needs of the pharmaceutical companies use the boiler area, the field and the actual situation of the site is determined to make the final, but strictly speaking, the venue for the pharmaceutical industry which is closely related with people, the more emissions low as possible. After the course, with regard to emission reduction technologies and the use of energy-saving technologies have in common is, the energy saving effect of this boiler is a comprehensive measure, based on a simple survey data, basically the transformation of low nitrogen gas steam boiler , basically thermal efficiency can reach more than 98% of the cost of running the boiler, ranging from 150,000 to 200,000 will be reduced, basically it will soon be able to return the cost of renovation. In short, low nitrogen gas steam boiler technology reform on the one hand can be appropriate to extend the life of the boiler, but also bring a certain margin improved for the enterprise value per unit time, is also possible to reduce emissions, it can be said to serve multiple purposes of effect.

7.2.1 Radiative Superheater. Radiative superheaters are used as the first heat transfer surfaces after the furnace. Often a platen arrangement is preferred to create a fouling-resistant construction. Spacing in the first superheaters can be from 150 to 1000 mm. Superheaters are the hottest heat transfer surfaces in the boiler, so they are often built with temperature-resistant alloys.Get A Quote
Pressure Switch For Steam Boiler - WHGLA. How to control the working pressure of a boiler - Quora. Most modern boilers are not controlled by an ON/OFF switch as they did in the past if automatic. A pressure switch with a cut out at high pressure and a cut-in at some span below the high cut-off is a tad old-fashioned, though still used in domest.Get A Quote
A Steam boiler is a steel pressure container in which water under pressure is transformed into steam by the use of combustion. In other words, the boiler is just a heat exchanger which uses radiant heat and hot flue fumes, released from burning fuel, to produce vapor and hot water for heating and processing loads.Get A Quote

Boiler Types and Classifications. There are two general types of boilers: ''fire-tube'' and ''water-tube''. Boilers are classified as "high-pressure" or "low-pressure" and "steam boiler" or "hot water boiler." Boilers that operate higher than 15 psig are called "high-pressure" boilers. A hot water boiler, strictly speaking, is not a boiler.Get A Quote
