china steam natural gas boiler

Comfortable life of people is inseparable from the northern winter heating boiler, normal, stable heat source is vital to people's lives. But the attendant is an increasingly serious environmental pollution problems, the implementation of coal to gas policy without delay, using the gas hot water boiler is the general trend. In order to achieve green heating, the National Tourism Administration Service Center decided to phase out the existing coal-fired boilers, the introduction of clean and environmentally friendly gas hot water boiler. Fast boiler with their own strong comprehensive strength and rich experience in the heating industry cooperation gained the trust of the National Tourism Administration Service Center, and ultimately provide a vacuum hot water boiler (T6-2800 2 sets of 2.8MW by fast Boiler ).

Steam boiler pressure controller function and debugging methods fired boiler, gas-fired boiler, china steam boiler 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.

Energy-saving measures and methods of industrial boilers which industrial boiler energy-saving measures and methods which 1, to increase the capacity and improve the thermal efficiency of boilers and inefficient small compared to the large-capacity high-efficiency industrial boilers, can greatly improve the utilization of energy rate, so as to obtain greater economic benefits. Meanwhile, the cogeneration project enables conversion of exhaust or extraction steam turbine for heating, not only can reduce the loss of turbine exhaust steam, but also help to save coal resources. Industrial boiler thermal efficiency of China's low is a fact that can not be ignored, usually operating efficiency even lower. Therefore, improving the efficiency of industrial furnace hot pot, is crucial for energy savings. In one aspect, by improving the quality of the insulating material, thicker insulation, heat loss can be reduced. On the other hand, the use of secondary air system, can facilitate a more complete combustion of fuel, the effect is very significant. 2, the heating surface to reduce coking and fouling of industrial boiler during running, prone to coking, fouling phenomenon, resulting in increased and then decreased local resistance to the flow cross section. Not only conducive to smoke, but also so that heat transfer is reduced, further increasing the temperature of the flue gas. Industrial boilers and cleaning agent has a good cleaning effect, can be put in the appropriate amount sublimation decompose at high temperatures, with the heating surface of the coke, slag and contacts a chemical reaction can be automatically off after decomposition. Meanwhile, a method of periodically purging is also more effective in the early formation of fouling was loose state can be cleared periodically sootblowing. If the attachment is too long time, will translate into close like fouling, thus increasing the difficulty of cleaning up. 3, to ensure the quality of coal and industrial coal-fired boilers with coal is crucial, its moisture, volatile content factor for the speed of fire, as well as affecting the combustion temperature is extremely obvious. Maintain proper moisture content can be reduced with reduced leakage occurrence of coal and fly ash, coal seam and helps enhance the evacuation ventilation. If the moisture content is too high, will affect the speed and the temperature in the furnace, heat loss will be increased exhaust smoke. Industrial water boiler heating surface for scaling impact of large scale for each additional 1mm, the overall thermal efficiency of the boiler will be reduced by 3%. 4, many factors affect the lower exhaust gas temperature industrial boiler flue gas temperature, within the course of the economizer scale, cleaning up soot neglect of smoke in the furnace wall channeling smoke, poor treatment effect, can cause elevated exhaust temperature. On the one hand, to deal with the heating surface appears slagging, fouling and scale phenomena take timely measures to eliminate, minimize or avoid their presence. On the other hand, on the rear of the boiler heating surface is improved or increased. Industrial boiler flue gas temperature, objectively reflects the utilization of exhaust heat. But not as low as possible, the exhaust gas temperature is too low but not conducive to the normal operation of the boiler.

It may be suitably improved electrical china steam boiler burner material: the electric steam boiler at the time of adjusting, if the wind speed control of the secondary is too small, it will lead to too close the gas fire, the burner nozzle so that thermally deformed until failure. Further, when the adjustment is not timely gas boiler load changes the level of the upper orifice of the secondary throttle will be cooled so that the burner is not burning. It may be suitably improved electrical burner of a steam boiler materials, steel materials excellent recommended to choose, and adding wear resistant features. Selection of swirler vanes refractory steel material, so to avoid burning due to swirling vanes configured fall burner opening deformation damage.
