gas fired steam boiler 2

Steam boiler pressure controller function and debugging methods fired boiler, gas-fired boiler, fired steam boiler 2 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.

Fast boiler is a research and development, manufacturing, sales of clean fuel boilers and boiler clean combustion technology of high-tech enterprises, including a boiler manufacturing and installation of Class 1 national A-level qualification. ABP has a single-family development center, single-family test center and two manufacturing area, producing a total area of ​​120,000 square meters, is one of China's boiler industry's leading companies with digital processing power, the products are exported to many countries and regions.

Classification and distinction and design a gas boiler, gas boiler gas boiler classified in accordance with the fuel can be divided into natural gas boilers, boiler city gas, coke oven gas boiler, liquefied petroleum gas boilers and gas boilers; according to the function can be divided into gas boiler water , gas hot water boiler (gas heating boiler comprising a boiler and bath gas), gas fired steam boiler 2 and the like; can be divided according to the structure of vertical gas boiler, gas boiler horizontal; in accordance with the process can be divided into a single flue gas boiler and tris backhaul backhaul gas-fired boiler. Second, the difference between fuel oil-fired boiler fuel boilers and gas boilers is fuel (such as diesel, oil, kerosene, etc.), fuel gas-fired boiler to gas (such as natural gas, city gas, biogas as well as liquefied petroleum gas, etc.), depending on the boiler What fuel burning device called a burner, boiler gas burner configuration called gas-fired boiler, oil boiler burner configuration called oil-fired boiler, oil-fired boiler and gas boiler difference is that what fuel burners. Third, the design of the boiler furnace by the gas boiler structural design pressure, provided through the top of the large pores, the boiler operates at atmospheric pressure, away from the danger of explosion; boiler furnace using computer simulation to optimize the design, the size of the boiler is fully optimized, so that coordination and beautiful form. Vertical-mounted boiler combustion at the burner, combustion of the fuel within the positive pressure furnace, baffle interposed smoke tube, slow smoke evacuation rate, to strengthen the heat exchanger, the heat furnace to ensure maximize fuel combustion water, improving the thermal efficiency of the boiler; horizontal wet back boiler full three pass structure, the length of the flue gas flow, reducing exhaust gas temperature, the whole corrugated furnace provided, so that the flame produced a strong turbulence to improve the heat transfer coefficient strength, and effectively It is prevented due to thermal expansion and contraction of metal results in a reduction of the life of the device; smoke tubes of large diameter and large pore bridge the gap, the boiler at equal time scale coating thin and easy to clean.

Gas-fired fired steam boiler 2 FAQ boiler for your boiler sorted out 30 common problems and solutions, do not forget to share a small partner after learning finished oh. 6, the main factors which influence the rate of wear of? ① flue gas, the concentration of the surface shape of the particle size and hardness ② ③ material in the flue gas flow rate of the material is worn element, the direction of relative movement of material with the hardness of the wear element ④ greatest influence It is the speed of the airflow, proportional to the cube of wear and speed. 7, how to control the bed temperature between 850-950? ① ash does not melt at the temperature, thereby reducing the risk of slag settle ② The temperature nitrogen having a high desulfurization efficiency ③ combustion gases at this temperature ④ less of the gas at this temperature the coal is not an alkali metal sublimation can be reduced slagging of the heating surface. 8, why should the torch boiler? Soda boiler system equipment such as part of desuperheating water, startup bypass, superheater, reheater piping system, due to the structure, material, arrangement, etc. are not suitable for chemical cleaning, so newly installed inside the boiler required physically remove remaining debris before officially put into operation, it is produced using the steam oven of the present systems and devices torch soda process. 9, common maintenance method, which has several boiler (1) Wet protection: with ammonia, liquid ammonia method, a method to maintain water pressure, steam heating method, a method of alkali, trisodium phosphate, and a mixed solution of nitrite Protection Act;? (2) dry protection: drying method (with pressure drainage) and desiccant process. 10, what? (1) steam with water vapor causes of quality deterioration (steam pollution). Boiler feed water containing impurities. After heating into the boiler feedwater into steam, most of the impurities are also transferred to the boiler water, so many times the cycle, increasing the impurity concentration of boiler water. Boiler water containing a high concentration of impurities is carried with the steam is called saturated steam water vapor with a machine called water carried, the first reason is contaminated steam. (2) steam soluble salt. The boiler at a higher operating pressure steam dissolves some salts, referred to as selective carry steam soluble salt, which is the second reason steam contamination.
