china d type water tube boiler factory

How to control china d type water tube boiler factory pressure correct? With the rapid development of the industry boiler, boiler becomes more secure, reliable, boiler explosion event frequency also declined. But this does not mean that the boiler explosion accident will never happen, an accident will cause serious irreversible effects to society, individuals. It is important to pay attention to is the pressure of the boiler running part, stay on top of the boiler pressure gauge changes, the boiler accident strangled in the cradle. Mainly refers to the boiler pressure boiler abnormal overpressure occurs, burst pipes, water hammer phenomenon, small will be analyzed according to the above points. A boiler overpressure overpressure is generated in a boiler pressure during operation is not normal, when the pressure exceeds the allowable range of the rapid increase in the specific performance of gauge pointer exceeds the allowable working line (typically a red indicator line), the operation of the safety valve occurs , the pressure continues to rise; also issued overpressure alarm signal to start the overpressure protection interlock mechanism; steam temperature increases to reduce the steam flow situation will change. Faced with this situation can be handled by the following four points. 1, to reduce the amount of combustion of the fuel, or valve manually open the purge valve for blowing off steam. 2, to increase the amount of water, treated sewage while strengthening the lower drum, thereby reducing boiler water temperature reaches the purpose of reducing the pressure in the boiler drum. 3, valve failure or if the pressure gauge has been damaged, should activate the emergency shutdown device to ensure safety valve or pressure gauge remains before starting the boiler is running normally again. 4. Finally, when taking blood pressure measures, we must remember that the buck can not be carried out rapidly, so that an explosion may occur during depressurization. Second, the phenomenon and the reasons for boiler tube boiler tube details see: a boiler superheater and reheater and its treatment method when the damage occurred. Third, the boiler water hammer water hammer refers to any polymerized condensate pipe sagging low water together to form a block, as the steam flow rate will accelerate the movement of steam, the block when the water changes direction suddenly, the kinetic energy of the water will be released, issued similar strong percussion sound of the pipe. Water hammer occurs when the boiler is usually accompanied by the following phenomena. 1, the boiler and the pipe connections clashed with a certain rhythm, accompanied by strong vibration water pipes or steam pipes. 2, the pressure gauge wobble frequency noise and vibration consistent. 3, when the situation is very severe, may lead to breakage of the connecting member of the flange, weld, valves and the like. Face water hammer phenomenon can be treated in several ways. 1, to reduce the amount of steam supply, the main steam valve can be closed when necessary. 2, a hydrophobic treatment open superheater header pipe and the steam trap on. 3, so appropriate in order to maintain the normal water level of sewage. 4, to ensure water supply and boiler water quality, prevent priming phenomenon. 5, the water hammer processed, to check use of pipes and connections butler, flanges, etc., on the timely replacement of damaged place.

Since this year, Qingyang City, Gansu Province Environmental Protection Bureau to continue to improve air quality at the core, in order to implement the Air Pollution Control Act as the main line, adhere to the rule by the people, source control, increase the comprehensive management of air pollution, construction of accurate and efficient and fine air pollution comprehensive prevention and control system, to fight air pollution control tough fight.

Qingyang Xifeng Kowloon City Road, South Street neighborhood community coal-fired boilers in accordance with the "clear" work requirements, continue to increase coal-fired boilers "cleared" efforts, multi-pronged, comprehensive treatment of the families of Xifeng Animal Husbandry Bureau building coal-fired boilers were removed.

Since coal-fired boilers to carry out "clear" its work, Kowloon South attaches great importance to the community, seven coal-fired boilers within the jurisdiction of actively deployed, timely follow-up, held a special arrangement will, continue to strengthen measures. In the community workers and urged many times to persuade, the District Animal Husbandry Bureau family member courtyard boiler successfully removed. After removal of this coal-fired boilers, coal-fired boiler demolition community task has been completed.

Phase out coal-fired boilers is an important measure to improve the air quality of the environment, but also the strong expectations of the masses. The demolition action, and effectively promote the area to carry out "the image of the city, the level of management" to work for the creation of a national civilized city to make its due contribution.

Common steam china d type water tube boiler factory overpressure accident approach: 1, the phenomenon (1) steam boiler overpressure sharp increase in steam pressure, exceeds the allowable working pressure gauge pointer over the "red line" safety valve after the pressure is still elevated. (2) the operation of the device is the interlock overpressure protection, should send overpressure alarm signal, stops the air blowing, the wind, coal. (3) steam temperature and steam flow rate reduction increases. 2, to treat boiler overpressure (1) weakened rapidly burning, manually open the valve or bleed valve. (2) increase the water supply, while the lower reinforcing blowdown drum (It should be noted at this time to maintain the normal water level of the boiler), in order to reduce the temperature of the boiler water, thereby reducing the pressure in the boiler drum. (3) as a safety valve malfunction or all of the pressure gauge damage, emergency shutdown, safety valves and pressure gauges are to be repaired after the boost operation. When endanger the safe operation of (4) Boiler excessive pressure, blood pressure should take measures, but too fast buck is strictly prohibited. (5) boiler overpressure eliminate serious, to the boiler furnace internal and external inspection, to eliminate the overpressure caused by deformation, leakage and other safety accessories and maintenance unqualified. Steam boiler accident and the type of treatment and the boiler safe to use common sense
