Food factory power generation lpg fired boilers china
Electricity is the foundation of industry. Today's enterprises, whether in production or in other areas, have a very large demand for electricity. Especially the food industry.
Steam lpg fired boilers china normal operation and normal operation of steam boilers and Management Working To do: strengthen the inspection of various equipment and instruments, to maintain the normal water level in the boiler, steam pressure stable, keeping the boiler room tidy, do shift work. 1, boiler feed water and requirements: In order to extend the life of the boiler, fuel economy, to ensure the quality of steam, to prevent scale boilers to cause slag corrosion damage and accidents member, the unit should use "industrial boiler water quality" in accordance with GB / T1576-2008 of provisions, the selected water treatment and oxygen equipment based on water quality and production requirements in the region, did not take reliable water treatment measures, the boiler must not be used. 2, the pot water level: always pay attention to the pot water level changes, to keep the water level within the normal range of ± 15mm can not be below the minimum level or above the highest water level in the water table generally slightly shaking phenomena, such as stationary water , the blockage may have a water table, should be cleaned immediately. 3, water table: class rinse water gauge at least once, to ensure that the water level legible, found glass washer leaking steam leakage when tightening the packing, there are two boiler water table, if one of them is damaged immediately shutdown until the repair can continue to run. 4, water supply equipment: Driving in the shift to check whether normal pump, if fault, repair or replace it immediately. 5, gauge: gauge bend should be cleaned once per shift, to view pressure gauge is normally found immediately shutdown to repair or replace damaged. 6, valve Note: a safety valve is normal, lever handle should be regularly carried out exhaust testing, the valve seat to prevent adhesions. 7, shift: To ensure safe and reliable economy class, fireman really good job following work should shift: (1) take over the boiler room fireman to arrive within the specified time, do succession prepare. (2) the shift fireman to do: boiler steam pressure and the water level is normal. Stable combustion in the furnace. Each device is operating normally. Each boiler accessories (including piping, valves, meters) safe, sensitive and reliable. Boiler room clean, tidy and well-lit. (3) To fireman serious and responsible to do the work and make shift operation records.
Recently, we learned: Rugao City, Jiangsu Province Supervisor Bureau Jiang Security Bureau adhere to safety first, prevention first, the principle of comprehensive management of energy saving, in-depth implementation of lpg fired boilers china production, sale, use, import and other aspects of business within the jurisdiction of the main energy saving responsibility inherent jurisdiction to conduct a hazard investigation work boiler.
Inspection process, City Supervisor Bureau Jiang branch of law enforcement personnel to go to boiler units, key to see whether there are coal-fired boilers, boiler inspection whether, whether for the use of registration, whether special equipment operator certificates, boiler safety management system developed and the status of implementation, boiler employees education and training, and emergency rescue drills to conduct audits, establish inspection records and ledger work, to maximize the elimination of security risks.
Up to now, there were still not found the use of coal-fired boiler of Unit within the jurisdiction. City Supervisor Bureau Jiang Security Bureau will continue to work closely with the various departments work together to advance environmental protection and ecological civilization construction work to further strengthen supervision to achieve a comprehensive cleared coal-fired boilers.
Why ash rear of the lpg fired boilers china heating surface steam temperature will reduce? In order to clean the boiler heating surface, reducing the exhaust gas temperature to raise the thermal efficiency of the boiler, heating surface, convection heating surface is mainly ash regularly. Since thermal efficiency boilers, such as maintaining the same boiler evaporation, the amount of fuel supplied into the furnace, the flue gas temperature and smoke velocity reduction furnace outlet, the heat absorption of the superheater heat transfer coefficient due to the temperature difference and the heat of the gas side lowering reduced, resulting in superheated steam temperature drops. The fuel quantity remains unchanged, the furnace exit gas temperature and smoke constant speed, due to increased steam flow and reduce heat absorption per unit mass of steam, superheater outlet steam temperature drops. Thus, convection heating surface ash, whether it is to maintain unchanged the amount of evaporation or the amount of fuel remains unchanged, so that both steam temperature drops.
