0 35MW-2 8MW Horizontal Gas Fired Hot Water Boiler
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.

Matters needing attention in using Electric normal pressure Boiler
At present, the hot high-grade electric atmospheric pressure boiler is a kind of thermal energy equipment with high temperature and high pressure. It is widely used in various industries, such as electric power, machinery, chemical industry and civil heating, which require the boiler to supply a large amount of heat energy. However, users are careful to pay attention to some items in order to ensure the normal operation of the equipment. So, let me give you the following interpretation of the operation of the atmospheric pressure boiler points for attention? The details are as follows:
1, attention should be paid to adjusting the water supply mode of the equipment at present, because the boiler and the system are separated from the system when the operation of the electric atmospheric hot water boiler is stopped, the users should pay attention to the operation of the electric atmospheric pressure boiler and the heating system respectively. In addition, the user should first put the boiler water to the lowest water level of the boiler expansion tank and then carry on the system water. At the same time, the gas in the equipment should be discharged when the system is filled with water. 2. pay attention to the test equipment ignition device before the ignition of the normal pressure boiler, the user in addition to the boiler auxiliary equipment inspection, but also should pay special attention to the automatic opening and closing valve opened is sensitive and reliable, but also should pay special attention to the automatic opening and closing valve opening is sensitive and reliable And pay attention to observe the boiler water level change, if the equipment stop running, its water level rises rapidly, it indicates that the automatic opening and closing valve leakage of the equipment is serious, the user should carry on the maintenance in time or replace the parts of the electric normal pressure boiler.
2, pay attention to the temperature change when the equipment is running, if the water temperature is too high, it is easy to cause the vaporization at the inlet of the circulating pump, so as to affect the normal operation of the equipment pump. Therefore, when using the equipment, users should pay attention to controlling the effluent temperature of the electric atmospheric pressure boiler, and the effluent temperature of the equipment should be controlled below 90 ℃. In addition, if the user needs a longer period of time to stop the operation of the more discounted electric atmospheric pressure boiler, the user shall close the valve of the boiler inlet and outlet. So that the circulating water in the equipment system is prevented from pouring into the boiler and the system height emptying phenomenon is formed so as to affect the re-start of the electric atmospheric pressure boiler.
WNS0.7-1.0 / 115/70-YQ: Horizontal representative of the internal combustion type gas 0 35mw-2 8mw horizontal fired hot water boiler, rated thermal power 0.7MW, Rated water pressure 1.0MPa, rated export / import water temperature 70 degrees Celsius and 115, respectively, fuel oil or gas. 1, rated thermal power: refers to the heat input per unit of time, common units kW kW or MW MW. There are some people to represent the output size of the hot water boiler tons.
In the winter season, Fushun City, the town of Dongzhou District hada Liaoning Province, this ancient village is undergoing a transformation heating, core change is the use of "provinces" biomass boiler.
Yao is the inventor in "provinces" biomass boiler. He said, "provinces" boiler, that is, to save money, labor, and material. Combustion and conventional combustion boiler essentially different, are in the normal combustion surface of the fuel from the outside and inside, top-down combustion, using a strong wind, or take pulverized fuel, and other physical and chemical techniques, cause the fuel in the shortest rapid combustion of the time. "Provinces" boiler contrary, starting from the bottom of the combustion of solid fuels, from the bottom up, a minimum amount of intake air by controlling the slow combustion. In 2013, the innovative energy-saving combustion technology obtained national patent, and Chinese Academy of Sciences Institute of Engineering Thermophysics, experts Tsinghua University, Tianjin University and Harbin Institute of Technology as "domestic initiative, the leading domestic" and suggested in our rural north conduct a comprehensive promotion.
Yao said in the last year, Dongzhou District not only invest in the construction of "provinces" biomass boilers, but also the laying of underground pipe network 3500 meters, central heating ancient village 30 farmers.
We understand that in 2016, Fushun City, has more than 600 households will be "provinces" boiler for the production and life. 2018, Fushun City, the ancient village of straw as a pilot village central heating, promoting the use of "provinces" boiler.
"With the gradual popularization of rural straw central heating, greenhouses can pick Heating, sustained economic heating greenhouses; straw waste form the commercial mode of operation into treasure, straw harvesting, transportation, storage, processing, a new farmers' income channels; the sky bluer, the water clearer, more green mountains, beautiful environment will inevitably become a new growth point of the rural economy but to embark on a modern intensive production, road projects of market-oriented operation, there is still a way to go. . "in Yao she said.
