Low Pressure Boilers

Low Pressure Boilers

Boiler reheat steam temperature abnormal phenomenon how to do 1, reheat steam temperature abnormal alarm. 2, when rapid change in the reheat steam temperature, turbine expansion, differential expansion, abnormal vibration or the like changes. 3, frequent accidents significantly reducing water damper action. 4, flue gas damper position is not adjusted properly. Cause 1, the flue gas through the large open shutter adjustment or control failure. 2, Save heated reheater out of adjustment. 3, low pressure boilers total wind excessive or too small. 4, furnace wall fouling, coking, fouling, resulting in furnace exit gas temperature is high. 5, reheater heating surface leakage, reheater tubes or burst at the occurrence of secondary combustion. 6, the high side mistakenly turned off after the adjustment is not properly heated Save high, high temperature steam. 7, squib reheat steam pipe. 1 process, or by warm water reheater flue automatic adjustment of the deflector is not normal, it is cut immediately to normal manual adjustment. 2, the case of excessive wind should be timely adjustment of the air volume is normal. 3, if the boiler furnace wall dirt, water wall for soot blowing to respond, if necessary, the main steam temperature can be appropriately reduced. 4. reheater heating surface leakage, the secondary combustion occurs squib or reheater, the result when the reheat steam temperature rises, in addition to quickly take measures to cool, but also processed separately according to the corresponding regulations. 5, sharply decreased 50 deg.] C over 10 minutes temperature reheat steam turbine side, should an emergency stop. 6, if the malfunction is high side, should be immediately shut down, and the next higher vapor temperature adjusted within a predetermined range.

February 20, 2019, the Beijing Municipal Government issued the "Beijing's pollution prevention campaign of 2019 Action Plan" (hereinafter referred to as the "Action Plan"). "Action Plan" clearly 2019 development goals: the first is the city PM2.5年均浓度, three-year moving average concentration strive to continue to decline.

Since 2018 autumn and winter, fog and haze in control efforts continue to increase. Beijing, Tianjin Fenwei Plain, the Yangtze River Delta region of the focus of supervision and maintain a high pressure situation, provinces and cities have also introduced Blue Sky Battle plan, air pollution control sector welcome the opportunity. And because the 2018 autumn and winter abolition of green "one size fits all", so that pollution from the administrative means to switch to environmentally friendly means to speed up environmental protection business orders release.

"Winning Blue Sky Battle three-year action plan" called for increased efforts to eliminate small coal-fired boilers, the county level and above urban area basically eliminated 10 tons of steam per hour and coal-fired boilers, in principle, to the new 35 per hour tons of steam coal-fired boilers. We believe that, under constant fog and haze, the small boiler phase-out process will accelerate. Research believes that by 2021 the transformation of coal-fired central heating investment 88.6 billion yuan, annual operating income of 240 billion yuan, the central heating market will also speed up the release with the environmental supervision.

Professionals expect non-electric air control about 192.2 billion market space, ultra-low emission thermal power market reform space of about 65.7 billion yuan, the whole vast air pollution control requirements.

In addition, the high diesel vehicle emissions, is also one of the main source of haze pollution. Considering the number of ministries had jointly issued by the Ministry of Ecology and environment "diesel truck pollution control tough fight Action Plan" diesel vehicles, boats become the focus of the next step of action to win the Battle of the blue sky.

When the oil-fired low pressure boilers without water or road accident ruptured action when the oil-fired boiler during operation without water, steam consumption for reasons outside the network losses, the situation may lead to boiler pressure drop, water and other furnace, because they can not supply water to the boiler , fireman should closely monitor water level gauge, pressure gauge, pressure gauge and found water table drops to limit prescribed run, shutdown should take measures to prevent water accidents. For various reasons when the pipe rupture accident occurred outside the network into the water in the system will be a huge loss, pressure heating boiler pressure less than the required operating pressure, but too large to fill water, large boiler heat loss, affecting the normal heating, should quickly Take measures. 1, first, determine the loss of pipe section, close the tubing segment, to minimize the impact on user heating. 2, organize personnel to repair and restore heating as soon as possible, while preventing the user during repairs to stop warming radiator pipes and cracking. 3, boiler operators to closely monitor fuel pressure gauge and thermometer readings, step up inspections to prevent accidents. 4, when a large amount of water loss outside the network must be shutdown, to deal with artificial pressure boiler taking fire, separated from the door, close the heating valve, open short-circuit loop. 5, after the troubleshooting is complete, water treatment confirmed intact before informing the boiler operation. These are the measures When the incident handling of oil-fired boilers without water or torn in hope for your help, of course, if you have any better way to welcome you to our online communication.

How to maintain the gas hot water low pressure boilers and now with improved quality of life makes many places there is gas hot water boiler, its appearance makes it even away from home can also enjoy the presence of hot water, it is precisely because the gas hot water boiler can provide consumers with a good living and bath with hot water makes a lot of manufacturers have chosen in order to provide better service to the people. So how should carry out maintenance after purchase gas hot water boiler? Maintenance method: general clean-up time even good brand gas hot water boiler also need to clean up on time, because long-term use will accumulate inside certain scale or slag, so try to stop using gas hot water boiler when the specified time will be able to follow its internal water drained and scale buildup inside to clean up. Maintenance Method Two: When using a regular heating gas hot water boiler in addition to clean up than the internal need them periodically or regularly use low heat an adjacent boiler steam boiler water is heated, the aim is to make regular gas hot water boiler inside the boiler water temperature can be within the normal acceptable time range of people and to avoid the winter freeze will not lead to the occurrence of burst condition occurs. Within a month the desiccant in the use of gas hot water boiler, and some users will be placed within the desiccant to keep the inside clean, but we must remember to put regular gas hot water boiler in the desiccant: Maintenance Method three need to be checked on time so as not to heat the interior surface corrosion phenomenon. But this does not mean do not need to be replaced, the failure of the desiccant is also the need for timely replacement. All in all, for any product or other items that need to be treated with caution, and only so we can let people enjoy more and better services. About three methods of maintenance gas hot water boiler is more for you on the hope that under the above can be maintained about the gas hot water boiler and clean life so that it can better serve the large number of consumers as well as their own.
