waste heat boiler Agent power generation process drawings

The reason industrial waste heat boiler agent power generation process drawings explosion and the cause of industrial boiler explosion hazards and hazards? For chemical plant before use, it must be to raise awareness of prevention. So as to avoid unnecessary losses to yourself. During boiler operation, the pressure exceeds a predetermined pressure to certain parts of elements, the thin portion will suddenly break, crack out immediately stored in the pot will be full of steam. In an instant, a pressure drop equal to pot the external atmosphere. At this time, since the momentum intense, so that part of violent boiling pot filled with water, the expansion, a small part of the whole pot steam also will be warmed, a pressure rises again, further expansion gap. Because full of water and steam in the rapid expansion of one-tenth to twenty second, when gunpowder exploded just as the rapid expansion of the gas, they become a powerful shock wave, with great destructive power. When the boiler explosion, due to the bursting of steam and water has a very high speed, or when the front portion in contact with air, will have a huge reaction, or moves off the boiler in the direction of the reaction force, rolling. Vertical boiler mainly in the blast site and calf ring potshell welding, explosion, steam, the water jet, and then pushed up Boiler fly. Horizontal boiler explosion member burners or more in the weld of the tube plate and the drum, the drum in contact with the combustion. When the explosion occurred, steam and water splashing forward or backward or downward, parallel to the fly boiler, boiler and rolling at the scene. A boiler explosion released energy is only a small fraction of the steel sheet to tear the boiler, in addition to steam and debris and the pipes, valves and the valve body is connected to the boiler, the energy transfer most of the other great shock wave in air, causing a large number of peripherals, badly damaged buildings, as well as the formation of casualties.

August 21 this year, is located in Tai'an City, Shandong Province People's Government issued the "Tai'an City 2018-- 2020 coal consumption reduction alternative work" (the "Program"), "plan" put forward the goal: by 2020 the city's coal total consumption control in less than 16.85 million tons.

"Plan" indicated, coal and other industries to promote the advanced production capacity instead of backward production capacity, optimize the layout of the coal industry, shutting down and eliminate small coal-fired boilers. Upon completion of the city's 10 tons of steam per hour and cleared of all coal-fired boilers, the city and county levels, no new urban area per hour and 35 tons of steam coal-fired boilers; 65 tons of steam per hour and higher fuel coal boiler completed the transformation of energy-saving and ultra-low emissions, reduce coal pollution, speed up the heating pipe network construction to expand the scope of central heating. Actively expand the consumer market in natural gas, fuel structural adjustment, encourage the development of direct supply of natural gas to large users to promote key industrial enterprises, industrial parks to achieve direct supply of natural gas. By 2020, natural gas consumption in the proportion of energy consumption increased to about 7%.

It is reported that the city will strengthen the clean-up before 2017 and shut down illegal projects, energy regulation and elimination of backward small boilers, small thermal power production, and resolutely prevent their return to work to resume production. And optimizing the layout of the coal industry, in strict accordance with the State-owned power plant deploy clean up illegal construction, and resolutely shut down coal units do not meet behind environmental protection, energy consumption, safety and other requirements. Meanwhile, on the basis of improving industrial enterprises above coal consumption data networking direct reporting system, increase audit statistics and law enforcement, and strengthen the quality of statistical data management, improve the accuracy and timeliness of coal consumption statistics.

Surface gas waste heat boiler agent power generation process drawings found to have visible cracks or other defects in time, we must pay more attention, if such cracks or defects have been unable to repair, it can only replace the entire device.

Use steam waste heat boiler agent power generation process drawings pressure gauge should pay attention to the following items: 1, rated steam pressure is less than 2.45MPa steam boiler, pressure gauge accuracy must not be both 2. 5; Rated steam pressure large or equal to 2.45MPa boiler, pressure must not be less than 1. 5 class. The dial diameter of the pressure gauge shall not be less than 100 mm to ensure that the operator can see the surface pressure indication clearly. 2. A red line should be drawn on the pressure dial of the steam boiler pressure gauge, indicating the maximum allowable working pressure. 3. Steam boiler pressure gauges should be installed in places that are easy to observe and rinse, and should be protected from the shadows of high temperatures, freezes and vibrations Ring. 4, steam boiler pressure gauge should be checked at least once every six months, after calibration should be sealed. 5, steam boiler pressure gauge connection pipe should not leak, steam leakage phenomenon, otherwise will reduce the pressure indicator value. 6. The range of the steam boiler pressure gauge shall be adapted to the working pressure of the measured components, usually 1.5 times of the working pressure, preferably 2 times of the working pressure. Steam boiler does not have a pressure gauge, the pressure gauge is damaged or the installation of the pressure gauge does not meet the requirements, steam boiler pressure gauge should be stopped when one of the following: 1, broken surface glass or dial calibration unclear; 2, no lead seal, lead seal damage or Beyond the calibration period; 3, when there is no pressure, the pressure gauge pointer of the finite pin cannot be restored to the limit pin, and the data of the infinite position gauge pointer deviating from the zero position exceeds the pressure coat allowed? Poor; 4, gas leak or pointer jump in the meter; 5, other defects that affect the accuracy of the gauge.
