gas steam boiler with cheapest price
Note the choice of industrial boilers from the first industrial revolution to develop microbial technology, and upgrading various products continue to emerge, led us to the development of human civilization from the original backward to technological civilization, to the boiler, for example, since the last century, there has been a cylinder since the boiler-shaped, with the needs of science and technology and production, from simple to complex, from single to serialization, boiler technology are developing rapidly, the good reputation of industrial boilers companies choose to share precautions industrial boilers; first, the coal use; the design of the cell structure based on coal boiler components as the design basis, select the boiler should pay attention to adjust to the type of coal in the region. It recommended new, high-efficiency, high-tech, high-quality, durable industrial boilers; second, parameter selection; industrial efficiency boiler work normally when approaching the highest efficiency rating, as the load decreases efficiency has declined. Boiler capacity is generally selected: it generates a large steam than the actual gas consumption, such as the required parameters and actual parameters difficult to match industrial boilers, high boilers in this case a gear selection parameter. Selection of auxiliary boiler should also refer to the above principles, to avoid the "big horse car"; third, the number of choices; normal maintenance of industrial boilers and boiler shutdown is a number of factors, but also pay attention to: the boiler room shall not exceed the number of boiler economizers work load, install boiler economizer device purpose is to avoid too much heat when the smoke away. Improve the thermal efficiency of the boiler, is provided in the back pass boiler economizer heating surfaces, the use of flue gas heating boiler feed water, to save energy, economizer after the installation, the boiler increases the thermal energy required for heating the feedwater, boiler water and so reducing the temperature difference between the water supply, reduce the burden of heating boiler feed water. Cause excessive number of boiler economizer can not play a role, resulting in waste of energy; These are high-quality industrial boiler company to share some notes selected industrial boilers; vast land of our country, many places are rich in coal, resulting in different types of coal , which has also become a basis for selection of parameters and select the number of boilers enable us to be more effective in energy conservation, to achieve a win-win.
Diqing in Yunnan Nonferrous Metals Co., Ltd. mainly engaged in Pulang copper mining, site selection, sales and other items. As we all know, in the copper smelting process, it consumes a lot of electricity and thermal power resources, which account for most of the hot water consumption. Combined with the actual demand Diqing company, to provide fast Boiler 1 stage electric heating hot water boiler of 2.1MW.
Steam boiler pressure controller function and debugging methods fired boiler, gas-fired boiler, steam boiler with cheapest price pressure controller and debugging method acting pressure controller is a pressure signal into an electric signal electromechanical conversion device, its function will be the high pressure or low levels of The electrical switching signal to the external circuit for automatic control or chain protection. Common pressure controller and pressure gauge, vapor pressure overpressure alarm can cut off the burner limit is reached; pressure controller adjusts single fire or dual fire burning the actual operating pressure; for large burner, the pressure may be adjusted according to the size of the size of the oil / gas, and always keep the pressure stable operation. Currently electrical contacts have been rarely used. Above the boiler pressure controller typically uses steam boiler pressure controller are used two to three pressure controller. Wherein a start and stop control furnace, for controlling a large and small fire conversion, there is used an overpressure protection. Two start and stop the boiler pressure controller is generally used to control the temperature controller, pressure controller is arranged to control the two-position and fire the boiler overpressure protection. Three safety accessories on the boiler must be in accordance with the procedures set two, which is intended primarily for safety. First, you can work to prevent another when one of them fails. Second, the purpose of comparison, in particular water level gauge and a pressure controller, to ensure safety, the operator to observe only one of which is the value indicated, but also controls the display shown two values match. 3 generally require a pressure controller, operation is as follows: the first is a power adjusting; e.g. a small fire is set 0.5MPa, 0.4MPa furnace start, the adjustable screw -difference pressure controller (hysteresis) is 1, range (set value) is set to 5. The second pressure is shutdown, diffe set to minimum, range adjusted to 6 (0.6MPa). The third overpressure alarm is set at about 0.7Mpa. Note: the pressure differential must first be transferred back controller adjustment process, and then transferred range. Gas steam boiler pressure controller debugging, generally follow the principle: high pressure, is used as the overpressure protection; high pressure, as boiler start-stop control; low pressure, as a large and a small fire conversion. Specific pressure range may be adjusted according to the nominal pressure boilers and the requirements of use.
