Matters needing attention and standard flow of boiler periodic sewage discharge operationOperational notes and standardized procedures for boiler periodic discharge: 1. Periodic Sewerage notices 1. The main value of the furnace should be contacted before the discharge is discharged, and the steam turbine can be approved before it can be carried out. 2. When discharging water level is normal, after discharge, check whether each sewage door is closed tight. 3. Sewerage doors should not be opened to more than 30s, can not open two or more sewage doors at the same time, in order to prevent damage to the water cycle. 4. Open the drain door slowly in case of water shock. In case of water shock, close the valve until the shock disappears, and then slowly open the drain door. 5. When operating the valve, you should stand on the side of the valve, strictly prohibited Right to the valve. II. Discharge operation flow 1. After receiving the scheduling task, labor protection supplies dressed neatly, with a special F wrench, on the spot open the general gate. 2. Open all the doors, contact the DCS screen of the furnace to open the corresponding discharge electric door, after the discharge, first close the second door, then close the door, one by one, one by one. All sewerage is over, close once door of each discharge and main gate of sewerage 3. When discharging water, we should pay close attention to the water level. If there is any abnormal water level or accident, the discharge should be stopped. For 2 hours, the door cores of each discharge door shall be checked for leakage, and if the drain is lost, the drain door shall be opened promptly once. Note by removing residue that may be stuck in the core of the door (boiler principal value should be contacted before operation): the whole drainage process should be in close contact with the DCS operator.
Gas heating boiler to replace the various components to achieve what state? After gas heating boilers after a long period of use, how much will be showing some of the damage, when the damage reaches a certain extent, the gas heating boiler will be scrapped. If its status as a criterion heating surface, then under what circumstances need to be replaced? First, measure the duct changes in the internal gas heating boiler, if a carbon steel pipe, then, once it's expanding crude exceeds 3.5% should replace lost; the steel pipe replacement criteria should be expanding crude exceeds 2.5%, more stringent . Secondly, for high temperature gas heating boiler superheater, the surface oxide if it has more than 0.6-0.7mm, and a deeper grain boundary oxidation cracks, crack depth than the grain size of 3-5, it will be It is considered invalid. Gas boiler heating surface 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. It should be carried out in accordance with the relevant standards for check pipe wall thickness and pipe gas heating boiler, ensuring accurate detection value obtained. Moreover, on the gas heating boiler economizer tubes, the amount of wear and if it has reached thirty percent of the wall thickness, it is necessary to replace. There will replace Similarly superheater, reheater water wall tube, wall thickness abrasion to reach 25 percent. Timely replace the gas heating boiler damaged parts, as long as the purpose is to not because they affect the entire boiler heating effect, guaranteed to always maintain a good working condition.
Gas boiler works and the principle of gas-fired boiler of a gas furnace gas fired boiler is also known, in general is natural gas, liquefied petroleum gas, city gas and other combustible fuel gas to heat utilization equipment, according to their functions can be divided into different type, such as a gas hot water boiler, gas hot water boiler, gas steam boiler fuel husk or bagasses, gas and other industrial boilers, gas boilers as China's coal-fired boilers have been banned since a new type of economic energy-saving products, it is widely used in the boiler civilian areas, mostly for heating and bath with. Here to share a gas boiler operating principle: the working principle of gas boiler and substantially conventional boiler is connected, is injected through the burner head of the burner into the furnace to ignite the combustible gas-mixed flame, so as to achieve furnace of the boiler, heating furnace tube, such as a good boiler Henan party shares fast production of gas boilers will be designed on the basis of these three return bend the combustion chamber or multi-backhaul goal is to deliver more local temperature, and because it is multi-cycle, high-temperature combustion smoke is produced after several times through the loop, the temperature in the discharge thoroughly complete transfer. The whole process is most important boiler with burner heads and fuel, together with the overall thermal efficiency of the superheater, the effective mating of these components reheater, economizer, an air preheater and the like to achieve the lifting of the boiler. These are the working principle of gas-fired boiler, where our customers want to buy gas boiler recommend a good product, Henan local production SZS series shares quick and efficient gas boiler, the product is currently one of the most advanced energy-saving equipment, 1 tons the gas boiler can save up to 10 cubic meters per hour of natural gas, it is a rare quality products.
