Coal-fired steam units produce electricity by burning coal in a boiler to heat water to produce steam. The steam, at tremendous pressure, flows into a turbine, which spins a generator to produce electricity. The steam is cooled, condensed back into water, and returned to the boiler to start the process over.For example, the coal-fired boilers plant in Indonesia heat water to about 1,000 degrees Fahrenheit (540 degrees Celsius) to create steam. The steam is piped to the turbines at pressures of more than 1,800 pounds per square inch (130 kilograms per square centimeter). The turbines are connected to the generators and spin them at 3600 revolutions per minute to make alternating current electricity at 20,000 volts. River water is pumped through tubes in a condenser to cool and condense the steam coming out of the turbines.
At the end of 2017, China Guodian is located in Jiangxi Province Wanan Hydropower Plant After evaluating the situation, some of the steam boiler used to purchase much-needed daily work. Sales Manager fast boiler combined with the actual situation of the power plant for its recommendation 2 0.5 tons of electrically heated steam boilers.
Why can steam boilers exemption? You can exempt steam boilers What are the benefits? According to the "Steam Boiler Safety Technology Supervisory Regulations" provides water capacity less than 30L in the boiler does not belong to the scope of the surveillance. According to the "Steam Boiler Safety Technology Supervisory Regulations" provides water capacity less than 30L in the boiler does not belong to the scope of the surveillance. The steam generator with plc controller water capacity of only 26L, like installing a home water heater as safe. So, Yinxing boiler steam boiler belongs to the exemption. You can avoid the security of small steam boiler What are the benefits? 1, you can not build a separate boiler room, can be placed in the basement, roof and other places 2, do not have a full-time duty Boilermakers (conventional boiler requires certified fireman) 3, eliminating the need for a year dealing with government departments, more peace of mind gas gas steam generators have any advantages over electric heating steam generator? Electrically heated steam generator is a small steam generating device. But steam production of electric heating steam generator is very small, and relatively low overall efficiency, the steam pressure generated steam temperature is relatively low, only suitable for use in the canteen steamed rice and the like occasions. Also much higher operating costs than on Yinxing gas steam boiler. The steam generator What are the advantages over conventional steam boiler? Steam boiler, is lower than conventional gas steam boiler safety running costs, fast start, no registration and annual inspection. Gas boilers suitable for use in what place? It can be used in hotels, factories, hospitals and other occasions. The hotel can be used as a steam boiler steam laundry places, canteens and other uses. As plant steam for a steam boiler may be used in the process. Steam boiler can be used as a hospital to disinfect hospital use. Free acceptance steam generator characteristics: 1, automatic water features: During operation, the pump automatically add make-up water, so the water level inside the work holder itself, it provides continuous high pressure steam to the external device. Without special care. 2, the triple pressure automatic protection to ensure safe and reliable devices: a weight Protection: when the body of the steam pressure reaches the upper limit of the pressure set by the controller can automatically cut off the heating power, when the body of reduced vapor pressure to the lower limit of the set , it can be automatically connected to the heating power, in order to ensure a substantially constant steam output pressure. Double Protection: the accidental causes the body to use the steam pressure exceeds the pressure limit set by the controller, the relief pressure automatically cut off the heating power controller. Triple protection: When the pressure in the pressure on the body due to an unexpected reason than the set limit safety valve, safety valve can be effective and timely release, in order to protect the safety of equipment and operating personnel. 3, dry automatic protection: accidental causes the water level falls under the level of the body, can be automatically cut off the heating power to ensure that the heating element will not be damaged due to the dry water. 4, is as a multi-chamber structure, two transition chamber by steam treatment, saturation is greatly improved, and a cool air discharging means, to ensure the quality of the steam, the steam quality requirements for higher user ideal. 5, the housing 304 drawing steel sheet, attractive and durable. 6, the control components used Schneider Electric or Siemens programmable and touch screen, reliable and durable. 7, plus turbo pump high-pressure pump, high pressure, low-power, reliable and durable. 8, a pressure and a water level automatic alarm device, a failure to timely processing.
As a top steam boiler manufacturer in China, ZG Boiler has been a premier provider of high-pressure industrial gas fired steam boilers for the industrial laundry markets for over 70 years. Our durable and simple horizontal design is a perfect fit for large industrial laundries factory. Because large size industrial laundries also utilize gas fired steam boilers to provide heat to the ironers, heated rolls, hot water storage tanks, and to provide steam using an unfired steam generator. Large industrial laundries are common in healthcare facilities, resorts, high-end hotels, and prisons.
