automatic horizontal gas 3 ton steam boiler
Lu Haiqing chairman welcoming remarks, welcome friends from afar, thanks they have been quick to support each other. As well as in-depth analysis of the current status of environmental demand and domestic gas boiler market, called on everyone to work together to accelerate the popularization and technical upgrading of gas boiler.
When gas boiler outage, we should not panic, there must be the order of the operation, shut off the gas boiler. 1, the normal shutdown sequence, check the gas fired boiler fuel, gas, water shutdown valve meets the requirements; 2, off gas, coal boiler blowdown valve to prevent the surface of boiler drum cause other problems; 3, quickly closing the main steam valve prevent dehydration gas fired boiler drum; 4, close the supply valve and deaerator power switch and gas valve.
Are gas-fired automatic horizontal 3 ton steam boilers environmentally friendly? Gas-fired steam boiler, which can be regarded as a gas-fired boiler, can also be regarded as a steam boiler. This boiler, from a professional point of view, is an environmentally friendly boiler, compared to oil and coal-fired boilers, because it uses gas. Moreover, the thermal efficiency of this kind of boiler is very high, can reach more than 90%.
Water wall boiler tube leak or burst phenomenon how to do 1, the normal water flow is not greater than the steam flow. 2, the furnace pressure transient and unstable prejudiced. 3, tube leak detection alarm device. 4, the furnace may not tight at the outward discharge gas and water vapor, and a significant leakage sound. 5, the main steam pressure drop. 6, boiler combustion dark flame instability caused by severe boiler fire. 7, when the induced draft fan is automatically cast, abnormal static vane opening is increased, the current increases. 1 reason, the presence of water wall tube material defects or post-production, the installation of the damaged pipe, poor welding quality. 2, the inner tube fouling overtemperature. 3, the inner tube corrosion. 4, water wall wear. 5, the long-term high load operation, furnace coking, coal sulfur corrosion caused by high temperature water wall. 6, improper combustion, flame deflection. 7, in the possession of bad foreign body, the water cycle. 8, the wall of the long-term over-temperature operation. 9, the temperature difference between waterwall tubes, mechanical stress crack. 10, the normal exit or drain sootblower steam punctured tube. 11, smashed chunks of coke furnace water wall tube or serious explosion occurred, resulting in water wall tube suffered external damage. 12, boiler overpressure long run. 13, the boiler starts to heat up, step-up too fast. 1 process, the leakage should try waterwall tubes outage. The leakage is not serious, while still capable of maintaining operation, note that each of the automatic operation when the device, if not normal, it is cut immediately to the manual, if necessary, may be down, down-load operation. Closely monitor the development trend of damaged parts, good accident anticipation, application shutdown as soon as possible. 2, if the leak is serious, the bursting point temperature after a sharp rise in quality work, leading to serious over-temperature wall, unable to maintain the normal operation of the boiler or threaten the safety equipment, emergency shutdown provision should be processed, when the steam temperature to protect the action value, the protection does not move, should immediately hand MFT. 3, note that the operation of the electrostatic precipitator, to strengthen the inspection checks, to prevent fouling, and the electrodes ESP hopper, pipes and the like plugging air preheater ash. 4, after the shutdown, should retain ID fan, the furnace pressure is maintained constant, there is no discharge to be stopped after soda ID fan.
