Henan gas boiler shutdown operation process: 1, electric control box Press Henan gas boiler "shutdown" button; 2, burner servomotor return to the initial position, the throttle valve is fully closed and gas; 3, solenoid valve and gas regulating safety valve is closed, the blower stops rotating; 4, after determining the water temperature is below 50 ℃, stop the circulating pump. 5, closing the manual gas valve; 6, close the water supply valve and return valve; 7, check the gas lines, water lines, air leak valve for leaks; 8, down air switch; 9, when the long-term without cutting Henan power gas-fired boiler. For more information Henan gas boiler: On the protection of Henan gas boiler - safety valve (a)

Further, the sulfur content of natural gas is also very small, and the coal-fired boiler dust removal, desulfurization, denitrification had on the gas boiler need only consider the problem of denitrification. 3, from the point of view of other waste emissions, natural gas, almost no other pollutants, especially in urban gas; and coal, then coal field (especially small boiler mostly built on open air) during the rainy season will produce slime water into groundwater import or surface water, after burning ash transport will produce dust. 4, of course, there are differences from other areas, for small boilers for gas-fired boiler energy efficiency is higher than a lot of coal-fired boilers, process equipment is simple, small footprint, low cost of operation and maintenance and so on.

Electric steam boiler of the heating process due to elevated water temperature within electric steam boiler, heating and evaporation of the bubble surface of the metal wall temperature begins to rise at any time. There are heating and wns hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. Since the bubble greater wall thickness, in the electric boiler of the heating process, the thermal stress is a major problem, it is necessary for the thermal expansion of the bubble temperature and thermal stress study. At the same time, also considering the overall thermal expansion problems, especially an electrical heating surface tube steam boiler, since the thin wall thickness, length of problems in the process of heating the whole of the problems of thermal expansion, it should also be noted that the thermal stress. Prevent inadvertent failure caused. In the process of generating steam and processing the thermoelectric pressure steam boiler, when the temperature is higher than the outer wall temperature of the inner wall, the upper wall at a temperature above the wall temperature, the wall thickness and the temperature difference between the upper and lower walls of the bubble there is a temperature difference, i.e., bubble the inner wall temperature above the temperature of the outer wall, the wall temperature is higher than the wall temperature, the temperature difference between the thickness of the bubble exists in the thickness direction, the upper and lower walls of the larger temperature difference between the bubble, when the temperature is higher than the outer wall temperature of the inner wall, the wall temperature is higher than the wall temperature. In order to prevent excessive thermal stress, it is necessary to gradually increase the pressure of the boiler. In the process of electric spark and boost steam boiler, the steam parameters of the boiler components, water and conditions are changing. Therefore, in order to effectively prevent the occurrence of abnormal conditions and other hazards, it is necessary to arrange a variety of instruments to monitor closely the instruction of professional change. Within the normal allowable range, but also the reliability and safety of various instruments, valves and other components was evaluated by adjusting the process parameters pressure, temperature, water, etc., in order to fully guarantee the security of the electric steam boiler stable operation. The higher the electric steam boiler pressure, the higher the energy, the corresponding steam plant, pipes and valves can withstand the pressure will increase, which also makes the maintenance and protection requirements of the steam boiler is relatively high. In the production and transportation, and the ratio of heat loss will increase the share of the steam.

Dairy production and processing sectors, need a lot of steam on food drying, sterilization, stereotypes, such as processing, steam boiler essential. Xinjiang Ake Su Xinnong Dairy Co., Ltd. as a local brand, has a large market users. 2016, Akzo increased demand for dairy production, the original steam boiler company can not meet today's production needs. In the same year, Akzo dairy cooperation with our company, signed a series SZS 6 tons of steam pipe steam boilers, steam support for the dairy industry dairy production Aksu.
