Boiler superheater tube overheating damage, why rely mostly in the middle of the rows of tubes? Because of the strong cooling effect both water wall boiler furnace, the flue gas leaving the superheater into the furnace, the temperature difference in the horizontal direction is larger. Flue gas temperature difference between both sides of the central and up to 150 ℃. High flue gas temperature, not only the temperature difference increases superheater tubes, and radiation heat transfer to the flue gas increases the superheater, the steam temperature in the middle of the superheater tubes increases. Increased thermal load, so that the temperature difference between the wall and the vapor rises.
Gas boiler must be done to protect the safety of 6 elements gas boiler is a special equipment, but also a pressure vessel, together with the fuel flammability, for various special nature of such equipment must ensure the safety of the operation of the gas boiler. 1, must be set on the boiler and flue explosion vent; 2, gas boiler must be installed in a gas leakage warning device and ventilation; 3, start and shutdown of the gas boiler must have a strict sequential control system; 4, the burner must be equipped with automatic flameout protection devices; 5, must often gas-fired boilers pipeline pipeline rigorous investigation, but also necessary to protect the furnace interlock control system; 6, gas boiler fireman who must be full-time person in charge of the gas boiler regular visits to check point.
Leak fault causes and how to do emergency measures gas boiler gas leakage accident occurred when using how do use gas in boilers, let's look at the leak accident: 1, gas boiler leak: it is needed to stop in time the furnace can press the emergency stop button. Followed by closing the valve of the total gas boiler, gas supply cut off, followed by the treatment plan is carried out according to the specific circumstances of the leak. 2, the burner leaks: need immediate emergency shutdown, to cut off the gas valve on the boiler and timely reporting to the company's safety and production departments, security leaks and gas boiler according to the process to develop detailed contingency plans, and find the relevant technical personnel. 3, indoor gas pipeline leak: an immediate need for emergency shutdown, but also cut off the gas valve boiler room, but also promptly notify the gas company and its safety and production departments reporting, according to a leak of natural gas and gas-fired boiler produce a series of emergency.
Six months from Hainan Sinochem Pharmaceuticals boiler equipment normally used in odd years, the equipment in good condition, our technical staff has repeatedly went to inspect the guidance. In the process of Hainan with the pharmaceutical companies, the other either for my company's product or service we are very satisfied with our company's reputation and expressed trust. --customer feedbackFree Chat
