720 KW hot water electric boilers
The inlet speed of gas-fired hot-water boiler before start-up should not be too fast, usually no less than 4 hours in winter, and 2-3 hours in other seasons, especially in the initial stage of water intake. The inlet temperature of a gas-fired hot water boiler is generally 50 °C, so the difference between the feed water temperature and the steam wall temperature in the drum is less than 40 °C. For gas-fired hot water boiler, the inlet water temperature can be equal to that of steam drum wall without complete cooling, otherwise the inlet water speed should be slowed down. When feed water enters the drum, it always first touches the lower part of the drum. If the difference between the feed water temperature and the drum wall temperature is too Large, the inlet speed is fast, and the upper and lower walls of the drum, the inner and outer walls will have a large expansion. Bad, on the drum caused a lot of additional stress, resulting in drum deformation, serious cracking. Due to the thickness and slow expansion of the drum wall, the tube wall connected to the drum wall is thinner and expands faster. If the inlet temperature of the gas-fired hot water boiler is too high or the inlet speed is too fast, the expansion will be uneven, the welded joint will appear cracks and the gas-fired hot water boiler will be damaged. The inner diameter of the decompression tube is usually φ 7~13mm (water and steam), and its length should not be too long (< 60m). Straightness of pressure pipe If the diameter is too small and the length is too long, it will affect the dynamic transmission of pressure measurement and increase the dynamic error. The inner diameter is too large to be easily maintained and installed. Pressure pipes should not be placed in the horizontal part to prevent the accumulation of bubbles (when measuring liquids) and water columns (when measuring gases). The pressure tap shall be perpendicular to the flow of the medium. Pressure faucet must not have chamfer, flange and burr. When measuring the hydraulic pressure of an electrically heated steam boiler, the pressure outlet should be removed from the lower part of the pipe to prevent the gas in the liquid from entering the pressure guide pipe; When measuring the gas pressure, remove the pressure splice from the upper part of the pipe to prevent dust and dust in the gas The droplets enter the ignition line. The installation site of the electric heating steam boiler pressure gauge (pressure transmitter) should meet the environmental conditions (temperature, humidity, vibration, etc.) used by the instrument, and should be easy to observe, repair and ensure safety. Insulation should be laid on pressure pipes in high temperature media to avoid burning during flushing. Pressure lines are equipped with needle valves (for cutting off pressure in the event of pressure line failures during operation), auxiliary needle valves (for use with instruments, stopping, replacement), condensing coils and elbows (isolation elastic elements from high-temperature media), Easy to install sealing gaskets) as well as sewage valves and sewers. For special pressure measurements, it's still pressing. Install discharge valve, isolation room and so on in the force pipe.
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. Steam boiler 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, burning more peace of mind coal, gas steam boiler have any advantages over electric heating steam boiler? Electric heating steam boiler is a small steam generating device. But electric heating steam boiler steam production 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. Steam boilers 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 boiler 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.
Mr. Lu Haigang mechanism for promoting the company's innovative company with a brief overview of the results related to the design and operation of the boiler were carried out on-site laboratory report. Mr. Jiang Zuojun hardware and software technology R & D infrastructure of the group now has a fully affirmed and expressed the company play a greater role in the adjustment of domestic environmental protection in low-emission structure expressed expectations.
