Matters needing attention in installation of Gas-fired BoilerGas-fired boiler also says that gas-fired heating boiler is a kind of boiler which uses gas combustion to heat water to satisfy people's heating. It belongs to the category of domestic boiler. By gas-fired heating boiler we usually refer to gas-fired atmospheric 1tons fired hot water boiler for rice mills, gas including natural gas, liquefied gas, city gas, coke oven gas, biogas and so on. There are explosion-proof doors on the rear of the fuel-fired boiler or on the smoke pipe, and the position of the explosion-proof doors should be conducive to the discharge of the explosion. In cases where explosive gas may endanger the safety of operators, a pressure relief guide tube shall be installed on the explosion-proof door. The installation of boilers, auxiliary machines and water treatment equipment shall be in accordance with the technical requirements of the equipment manufacturing plant. . The equipment foundation must wait until the equipment arrives and checks correctly with the design drawing before construction. 3. When installing the equipment, avoid the equipment, and the installation material should be stacked on the floor. When using building column, beam lifting equipment, the bearing capacity of beam and column must be verified in advance. 4. After installation of oil, gas, hot water and steam pipes, the pressure test acceptance shall be carried out according to the Code for Construction and acceptance of Industrial Metal Piping Engineering GB 50235 / 1997.

What works and characteristics of natural gas boilers are? Gas-fired, the main structure of a shell boiler, furnace, turning smoke chamber, and other components of the smoke tube boiler is suitable for light oil, heavy oil, natural gas, gas and other fuels, the boiler reasonable structure, double-layer anti-burn, facilitate flue gas is fully utilized, and also has a small footprint, easy installation, high steam quality and so on. Works natural gas boilers are: water through the inlet into the boiler, heating boiler after heating meet the water quality standards, into the interior through the radiator circulating pump to heating by radiation and convection heat transfer, water flowing through the radiator, back inside the boiler is heated, and then again into the radiator, so the cycle is carried out. And the system of gas-fired, can also provide hot water to meet their basic needs, the boiler water temperature and the indoor temperature, a temperature sensor after the treatment, the temperature signal is transmitted to the microcontroller, through the corresponding drive circuits to adjust corresponding pipe size valve, and further by controlling the temperature of water, heating to achieve the purpose, the user according to the size of the heating range, select the appropriate circulating pumps, to do so is also more economical and convenient.
Gas fired 1tons fired hot water boiler for rice mills are designed as per the combustion characteristics of fuel oil and gas, improving heat transfer, reducing smoke emission temperature, decrease dust, SO2, NOx emission.
