Henan Gas list of companies in ncr supplying boilers tube phenomenon and treatment 1, Henan gas pipe explosion phenomenon: you can hear the sound of soda injection time (1) squib, severe obvious explosions. (2) becomes pressurized combustion furnace by the combustion pressure, and ejecting the smoke and steam from the oven door opening and large air leakage at the furnace walls. (3) water flow is not normal, greater than the steam flow. (4) Although the increase of water supply, but the water level is often difficult to maintain, and the steam pressure reduced. (5) The exhaust gas temperature decreases, the color of white smoke. (6) furnace temperature is lowered, and even fire. (7) draft fan load increased, the current increased. Bottom (8) Henan gas boiler water flows out, an increase in ash. 2, Henan gas boiler tube process: (1) tube burst leakage is not serious and can maintain the water level when the accident is not to expand, maintain the operation load can be reduced for a short time, and then start to be standby furnace shutdown. (2) cracking furnace tube can not maintain the level, should an emergency shutdown, the induced draft fan should stop, should continue to Henan Sheung Shui gas boiler, reducing the wall temperature, the accident will not re-expand. (3) as a result of water shortage in Henan gas boiler, wall overheating when burst pipes, should an emergency shutdown, and prohibited the boiler feed water, then should withdraw from the furnace over the fire as soon as possible, reducing the furnace temperature, reducing the degree of boiler overheating. (4) if several parallel for the steam boiler, a main steam pipe and the steam should be the parent partition tube boiler accident.
The effect of Henan Gas list of companies in ncr supplying boilers feed water temperature of the boiler in order to improve the thermal efficiency of the entire plant, Henan power plant is equipped with gas boiler feedwater heater, the heater previously referred to pump low pressure heater, after giving the high-pressure pump called heater. By high pressure feedwater heaters, water temperature greatly increased. For example, medium pressure feed water temperature of the boiler mostly heated to 172 deg.] C, the high pressure furnace was heated to 215 deg.] C Usually, ultra-high pressure boiler feed water is heated to 240 deg.] C, sub-critical pressure boiler feed water is heated to 260 ℃. When the high pressure feed water heater due to the leakage of high-pressure heater water splitting in operation through the bypass to the gas boiler. Henan gas boiler feedwater temperature is lowered, the fuel portion of the heat to be used to increase the water temperature. If evaporation unchanged, will increase the amount of fuel, the furnace exit gas temperature and flue gas flow rate must be increased to increase the heat absorption of the superheater, the steam temperature is bound to increase. After Henan gas boiler feed water temperature decreases, assuming the same amount of fuel, since the portion of the heat used to increase the fuel water temperature, reduce the heat to generate steam for the evaporation of time due to the combustion conditions constant, smoke Furnace Outlet constant temperature and flue gas velocity, the superheater heat absorption is not reduced. However, due to the reduced evaporation, steam temperature inevitably increases. Therefore, water temperature decreases, the temperature of the steam will inevitably increase.

Projects and programs as Xiamen Rui Yi Hotel Xiamen City landmark hotel building, attaches great importance to environmental protection philosophy, which party fast list of companies in ncr supplying boilers manufacturing philosophy coincide. In late 2016, the two sides signed an electric steam boilers for hotel supplies disinfection work, since the electric steam boiler, any security incidents never happened, Rui Yi Hotel ensure normal operation.
Boiler leakage of pharmaceutical and correct operation of the list of companies in ncr supplying boilers leakage causes and correct operation method pharmaceutical methods commonly used in the pharmaceutical boiler is a steam boiler, in the course of its use because of improper boiler operation, there may be some or that kind of problem where flue boiler corrosion caused by water leakage problem is one of them. The reason for this phenomenon a. Boiler feedwater oxygen scavenging process is not performed, resulting in chemical oxygen should, boiler, or other ingredients of the metal parts, boiler corrosion occurs, not in time for a long time, causing the boiler water leakage. b. routine improper operation, shutdown did not close when the water supply valve or the steam valve main pipe, air into the furnace, and again use the boost, the incoming oxygen is not timely removed, so that in a hot and humid environment caused by oxygen long-term corrosion perforation of the smoke pipe. Precautions: in strict accordance with standard operating a steam oven in accordance with operation of the boiler feedwater standards GB1576-2008 oxygen, reduce the oxygen content, avoid the presence of oxygen, chemical corrosion. b. When shutdown, when the boiler is in the normal high water level shutdown and normal pressure, and then close the inlet valve and the main valve, to prevent intrusion of outside air oven. c. boiler room to keep dry, clean, ventilated, while the process of personnel to operate the fireman to be precise, compliant. d. strengthen valve maintenance, maintaining rigor. In short, there are many reasons causing leakage of pharmaceutical boiler, but if the mistake is due to improper operation caused by the boiler, it should be noted in particular the normative operation, prudence, as far as possible preventive measures.
