A wide range of supercritcal boilers for power plant plant is available to suit most factory requirements; the choice being dependent upon local conditions. Where positive economic thinking dictates that only bagasse shall be burnt as a fuel, the boiler fitted with a self-feeding furnace very adequately meets these requirements. Further in areas where skilled operators are at a premium, this unit provides broad operating characteristics without the need for sophisticated control systems. In areas where skilled labour is readily available and a maximum degree of mechanisation is required, the air
How to avoid the use of gas steam supercritcal boilers for power plant accident? Rapid social and economic development so that is also extremely fast, and gas steam boiler as heat and power production process equipment, and people's lives are commonly used in industrial applications among development of modern industry. There are a lot of engineering to be used as a gas boiler steam heating equipment. However, if there is improper operation in the operation, it is very easily lead to accidents and leaks, not only a threat to people's lives can also cause economic losses. So how to avoid accidents when using gas steam boiler? 1. Before purging gas steam boiler to prevent the ignition of superior quality gas explosion incidents usually have some protection measures, but still needs to make a purge of the boiler furnace and flue gas channel before the launch, but also the need for the gas supply gas purge conduit. A medium gas supply pipe purged generally used inert gas (such as nitrogen, carbon dioxide, etc.), and the purge of the boiler furnace by the flue must flow velocity of the air as the purging medium. After purging, if time is not on fire, then they must then purge the furnace flue, before a second firing. 2. If the quality of exhaust smoke rigorous testing quality standards, on the one hand the discharge of smoke and dust can cause air pollution, on the other hand may also lead to excessive levels of indoor carbon monoxide and cause some accidents, so, in order to ensure environmental protection and safety, gas steam boiler fireman who should be among the adjustment incineration process, the exhaust components of the boiler rigorous testing to determine the excess air ratio and incomplete burning conditions, to ensure the safe use of gas steam boiler. If companies can purchase gas steam boiler trusted to use, and pay more attention to purge the furnace, the flue gas channel before ignition, as well as smoke testing in accordance with strict quality practices in the use of gas steam boiler, thus can effectively improve the safe use of gas steam boiler factor, making it possible to avoid all kinds of accidents.
(3) boiler leakage serious. Excessive cold air into the furnace, the flue gas oxygen increased, when the smoke detector detects smoke oxygen than 8% oxygen, there will be excess air, it generates heat loss. It may be determined by detecting the leakage of flue gas oxygen.
Meanwhile, the party also fast supercritcal boilers for power plant design automation control systems, temperature, pressure, and other parameters automatically adjust the water level, real-time monitoring anti-smoke temperature, oxygen content and changes in safety interlock, even if unattended, the boiler can function . In mid-January 2019, under the fast boiler joint efforts of all staff, boiler manufacturing is completed, the pipeline project has reached Hwashi ground, and successfully complete the installation and commissioning work. At present, the boiler has been put into the urban underground pipeline construction and maintenance projects in order to contribute to building a better city.
Each ultra-supercritical boiler of the plant will be capable of generating steam at 600°C and 270kg/cm² pressure at the turbine end. Each 660MW steam turbine of the plant will feature one high-pressure (HP), one intermediate-pressure (IP), and two low-pressure (LP) cylinders.Online chat
In addition to this, the supercritical boiler technology also helps in achieving about 3-4 percent higher plant efficiency compared to conventional subcritical design. Supercritical technology is the most adapted to address Indias challenges for coal power generation additions.Online chat

Jan 15, 2019 · What is boiler? A boiler is an enclosed pressure vessel in which water is converted into steam by gaining heat from any source (coal, oil, gas etc). Boiler in thermal power plant accumulates the steam and build up a pressure to expend it in turbine and convert thermal energy to mechanical energy.
