natural gas steam fire tube boiler

Electric steam fire tube boiler supplying domestic matters need to pay attention what? 1, electric boiler carefully check each system before opening oven parts electric boiler, focused on checking the three security controls pressure gauge, safety valve, gas pipe fittings, water level is normal, everything is correct, put on compliance clothing to continue to work. Electric steam boiler 2, please do one-handed operation when the water in the electric boiler, water regulatory action is single-handedly opened the door in one hand and a water injector steam valve, when the water column to a predetermined level, the first valving (valving time face not being on the water, to prevent splash injuries face) and then turn off the water gate, electric boilers provide domestic water to be alert order can not be reversed. When electric boiler work, surrounding someone must guard the moment the water level and pressure gauges, there can be no neglect of duty, to adjust work schedules when working at night, night shift work, be sure to have a good rest during the day, not at night when this work I would doze off, because if there is any carelessness, accidents will happen. Points to note what? 4, electric boilers night to the boiler daily sewage treatment, water table should clean up once every night. For motor and other mechanical equipment have always been its inspection, if any abnormal findings, the investigation must be immediate. Weekly safety valve should be checked whether it is safe.

The need for paper industry paper industry conversion of coal-fired steam fire tube boilers to gas boiler is a boiler equipment industry needs is more important, because a lot of links to the papermaking process requires a lot of steam drying, stereotypes and so on. However, along with the national policy of environmental protection departments to ban coal-fired boilers, and now more and more manufacturers have to use coal-fired boilers to coal-fired boilers upgrading or purchasing a new low - NOx emissions. Paper mill boilers from coal to gas fired boiler is an important direction of current reform, is one more type of enterprise transformation, especially in the area more natural gas, coal into gas boiler is the main way. 1, in order to transform mechanization layered fired boiler gas boiler, you should first remove the front arch and a rear arch, while increasing the bottom heating surface, instead grate, grate to prevent overheating, combustion; 2, through the furnace heat transfer calculation methods determining the size of the boiler, furnace flame center position, and then pouring furnace work. In order to avoid the center position after arch boiler tubes, based on the original slope of the original arch made pipe. 3, the furnace in order to prevent an explosion, when the coal-fired boiler furnace gas is substituted, or when fuel not atomized combustion gases in the furnace incomplete combustion or heating surface of the end of the furnace, a fire or explosion occurs, should be mounting the appropriate parts of the boiler explosion vent, and to increase the ignition and flame failure protection program control to automatic control means, to ensure safe operation of the boiler. 4, is closely related to the selection and arrangement of the burner and furnace, the filling degree of the flame in the furnace should preferably not to form a dead air. Gas burner arrangement considered reasonable and piping layout, easy operation, maintenance and inspection.

Jingzhou City, Hubei is located in Jianli County Supervisor Bureau for a food processing plant emergency inspection and maintenance, the timely processing of the security risks of the steam fire tube boiler. At the meeting held later, the city supervisor Bureau emphasized the specific guidance boiler safety management.

Steam steam fire tube boiler which automatically displays the instrument will encounter problems in accordance with the steam boiler fuel can be divided into electric steam boiler, steam boiler fuel, gas steam boiler using the water level; in accordance with the constitution can be divided into vertical steam boilers, horizontal steam boiler, small steam boiler mostly single, double the return of the vertical structure, large steam boilers and more horizontal structure of three return. There lowland water or a display apparatus using the automatic water level when the water level in steam boiler water level is only a low level of installed devices, and even water pipes are too small; the water level or a Low level using the instrument, when the steam boiler is automatically displayed only one water; a water drain device, drain cocks no ground; on a drum water level is effective, other water damage; plug screwed on the fixed level; on tap water gauge leak, leaking; water false water level on the display unit; the drum water level in the two water gauge level of inconsistency; water is often broken glass; water gauge glass without guard; a water gauge glass plate not shown in the red line indicating the water level; water gauge glass plate is dirty, the water level observation is unclear. Steam boiler water level glass observation level of inconsistency and the main reason is unclear steam boiler for long periods of time rinse in running water, a daily maintenance is not carried out, resulting in water cock rust, gas, water and even the block, or insufficient packing or aging deterioration. False water level phenomenon, in addition to gas, water or even the cock pipe is blocked, but also could be vapor, the water pipe connected to the water level due to misalignment connected; steam, water tap handle installed the wrong position resulting cock closed, since there poor water quality, the water level in the boiler and false priming. Water gauge glass is broken mainly steam, water faucet centerline not aligned, the presence of glass bending stress; long glass without expansion gap; water gauge is being cold draft at window glass, and glass pipe quality was poor. During the operation of the boiler, the water level was found is not clear, to shutdown immediately ultra-high water level, timely detection of problems.
