Now for the question of natural gas high quality food hygiene chinese double boiler service life, we should understand it, Henan fast boiler manufacturers of gas-fired equipment, to ensure the life of the boiler is more than 10 years, if then a good, stable maintenance, for 20 years there may.

2, non-uniform flow of steam high quality food hygiene chinese double boilers.

Different evaporator heating surface pressure variation parallel flow resistance of each tube and along the length of the distribution header, and re-position the head can be different between the respective tubes to cause uneven flow.

① variation on the thermal flow resistance. Since the structure of the steam pipe, the quality, of different length, diameter, roughness and curvature, which are not the same resistance to flow, under the same pressure conditions, the size of the resistance will cause uneven flow.

Problem analysis of the deformation of the heating surface of the steam high quality food hygiene chinese double boiler 1, the heating surface modification phenomenon a. Waterwall tubes or deformation of the door to see the fire door from the saw, when accompanied by water, can see the red curved water wall tube. B of the horizontal combustion furnace of the boiler, can be seen from the observation hole furnace wall to the fire front side of the deformation. 2. Heating Surface modification of a. Serious boiler water, heating surface of the cooling pot of water had to be thermally deformed. b. poor design structure. The local circulation flow rate is too low, stagnation, that the wall temperature exceeds the allowable temperature deformation. c. Install error, the pressure receiving member is not free to expand. D. substandard quality, thick scale, excessive water residue.

Heating and hot water daily is an important basis for maintaining the northern region of the normal operation of enterprises; for Legal Daily organs and units, the hot water high quality food hygiene chinese double boiler is one of the indispensable energy equipment. Currently, work is facing north Heating equipment and facilities aging, increase energy conservation and environmental protection requirements and other issues. Daily logistics-related legal person responsible for improving the overall level of heating units, and the response advocated by the national energy saving, plans to purchase energy-efficient heating boiler. Considering the increasingly stringent environmental policy, Legal Daily authorities decided to use natural gas as boiler fuel. Fast boiler for 20 years, specializing in the production brand boiler, which had been successfully assisted more than Beijing enterprises and institutions, to provide clean heating. The party technical consultant fast boiler based on actual usage Legal Daily units, providing commercial condensing units 99KW vertical 1 hot water boiler.
