The method of starting the boiler during boiler startup control drum wall temperature difference of the process to be controlled in a predetermined drum wall temperature difference may take the following measures within 40 ℃: (1) water temperature before ignition can not be too high, not too fast speed, according to rules of execution. (2) water is completed, the bottom may be put into steam heating conditions. (3) strictly control the raising rate, in particular 0 ~ 0.981MPa boosting speed stage should be less than 0.014MPa / min. Rate of temperature rise not greater than 1.5 ~ 2 ℃ / min. (4) should be regularly switching angle oil gun, until the next row when four full cast oil gun, each part as far as possible evenly heated. (5) via the above-described operation can not effectively control the drum, the lower wall temperature, then when the approach or reach 40 ℃ booster should be suspended, and the sewage regularly, in order to enhance the circulating water, and stabilized until the temperature difference is less than 40 ℃ line boost.

Office module using gas boilers, which purchase criteria? How gas boiler energy-saving, environmental protection and smart combined in one, fast Boiler invested considerable money and effort, concentrated study, launched the boiler equipment meet the above criteria - gas boiler module.

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 boiler 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.

Industrial plant boiler cleaning method which: industrial plant boiler cleaning method What? For industrial boiler plant, the run for some time are to work descaling, if not timely cleaning, for normal operation of the industrial boilers, will have a great impact. Clear boiler scale methods, mainly mechanical descaling and chemical descaling two kinds. Mechanical descaling by the people directly into the drum, spatula or heating surface cleaner to remove scale. However, this method is labor intensive, easily damaged heat transfer surface roughness increases heat transfer surface, not completely clear, it has been rarely used. Chemical cleaning commonly used cleaning and corrosion hydrochloric acid two alkali cooking method, cleaning method which should be taken according to the kind of fouling layer. Alkali cooking method is run in the soda furnace (of Na2CO3), caustic soda (NaOH), or trisodium phosphate, longer times boiling out at normal operating pressure.
