howto make steem boiler
Henan gas howto make steem boiler installation requirements for the gauge 1. Pressure gauge installation should meet the following requirements: ⑴. Henan gas boiler installation position gauge, should be easy to observe and rinsing, the dial should be tilted forward 15 °, and should prevent affected by temperature, vibration and the like freezing. ⑵. There should be a trap between the pressure gauge and gas-fired boiler drum Henan. Steam or hot water in which the spring and then into the cooling pipe, to avoid reading errors caused by high temperatures, even damaged parts in the table. The inner diameter of the trap, with the brass when not less than 6mm, when using steel not less than 10mm. A lower portion of the trap, preferably equipped with drain cocks, water to let go of the tube after shutdown. ⑶. It should be fitted between the water gauge and the three-way stopcock elbow, and to flush the pipeline inspection, check, unloading gauge change. a. When normal working pressure gauge, Henan gas boiler media through the trap and pressure gauge connected, the pressure gauge pressure boilers. b. Check the pressure gauge, Henan gas boiler and pressure gauge cut off, the pressure gauge to the atmosphere, because there is no pressure in the table, so if the pointer back to zero can not prove that the gauge has failed and must be replaced. c. When flushing the trap, Henan gas boiler with the atmosphere, with the pressure gauge cut off, the trap in the water and dirt, the boiler blowing in the media. d. So that when water in the trap, the trap and the air pressure gauge are cut off, Henan gas boiler steam or hot water is gradually accumulated in the trap was cooled. e. When checking pressure gauges, while communicating with the boiler working pressure gauge and check the pressure gauge. Standard gauge calibration connected with the flange on the left side of the three-way cock, the medium from the working pressure into the trap and simultaneously checking the pressure gauge. Pressure gauge indicates the two values, the difference shall not exceed the gauge tolerances specified otherwise, the work proved inaccurate pressure gauge, pressure gauge must be replaced. Three-way stopcock handle end portion, the plug must be marked with an arrow indicating the direction of passage in order to identify. When the three-way stopcock operation, action to slow, to avoid damaging the gauge parts. ⑷. Even if long tube pressure gauge, the valve can be installed (or cock) close to the connection pipe at boiler drum Henan gas for use in the maintenance of the cutting gauge and accessories. However, in operation, the valve must be loaded (or tap) the hand wheel (or handle) Remove or lock to prevent accidental off and cause a major accident. 2. When the pressure gauge of the following circumstances, should stop using: ⑴. Limited nail no pressure gauge, the staple rotation pointer does not return to the limit; not limitation staple no pressure gauge, a pointer value from the zero position more than a predetermined tolerance gauge. ⑵. The surface of the glass or ambiguous dial scale. ⑶. No seal, the seal is damaged, or the Verify the expiration date. ⑷. In the table pointer leaks or beating. ⑸. Other effects gauge accurate defect.

Gas fired steam boiler
First, what is condensing howto make steem boiler
More energy-efficient condensing boiler is a special equipment to save money, according to their capacity needs of different industries, ranging from 0.5 to 20 tons; compared with the traditional boiler with high thermal efficiency, safety, noise, environmental protection, pollution-free advantages.
Recently, Taiyuan, Shanxi Province Environmental Protection Leading Group issued a circular on promoting the transformation of ultra-low emissions and low nitrogen transformation of biomass howto make steem boilers gas-fired boiler. Resolutely implement - the latest requirements "2018 in Beijing, Tianjin and the surrounding areas in 2019 autumn and winter tackling air pollution comprehensive management action plan" in, and further reduces boiler emissions standards.
Located in urban construction area of biomass boilers to complete the transformation of ultra-low emissions at all before 31 October 2019. After the transformation to achieve ultra-low emissions coal-fired power plants. 6% of the oxygen content of the reference, soot, sulfur dioxide, nitrogen oxides emission concentration of not more than 10,35,50 mg / m. Rear of the boiler can be installed efficient dust removal, desulfurization apparatus or stock updates Ultra Low NOx emissions (nitrogen oxides emission concentration is not higher than 30 mg / m3) gas boiler or an electric boiler.
December 31, 2015 installation of ultra-low nitrogen gas boiler to complete the transformation of the October 31, 2019, after the installation of gas boilers used to complete the transformation of the ultra-low nitrogen October 31, 2020. After transformation of nitrogen oxide emissions concentration up to 30 mg / m. District heating gas boiler discourage updated low nitrogen burners, home improvement flue gas recirculation device to transform the way, is updated to encourage direct ultra-low nitrogen emissions boiler.
