Fuel (gas) steam boiler WNS4-1.25-YQ thermal efficiency up to 90% steam temperature ..

Henan Yongxing Boiler Group: Fuel (gas) steam boiler WNS4-1.25-YQ series official website: www.hnyxboiler.com Tel: 18238907969 WNS is a horizontal type gas boiler combustion quick three-pass fire tube boilers. With a bias furnace wet back structure, high temperature flue gas in order scouring second and third return pipe tobacco, and smoke from the rear chamber through the chimney into the atmosphere. Events around the boiler is equipped with smoke cover, easy maintenance of the boiler. Boilers with good technical performance burners, combustion using automatic ratio adjustment, feedwater automatic control, program start and stop, automatic operation and other advanced technologies, and has low water level alarm and low water level, high steam pressure, turn off automatic protection function . The boiler has a compact, safe, reliable, simple, quick to install, less pollution, low noise, high efficiency. Main features: 1, the overall structure is reasonable and compact, is a boiler island, in line quickly factory conditions. The product consists of three parts at the factory; boiler host, chimneys and piping systems, where the host and chimney section have been completed in-house manufacturing, the host supporting the pipeline valves, meters have been installed properly randomized, transported to the site will host and chimneys can be assembled. Site turned gas supply, power supply, water pipeline to test. Shorten the installation cycle, and can ensure product quality. 2 design and advanced performance. The boiler host belongs to the whole structure, the burner assembly on the front cover of smoke, the main body portion is arranged heating surface and the combustion chamber. With a reasonable structure, compact, low consumption of steel, furnace with a bias waveform furnace, insulation use of a new lightweight insulation materials, packaging using a color sheet packaging is rectangular shape, so that the boiler performance, weight, structure, size , appearance and domestic goods the same capacity it has obvious advantages compared to the perception of beauty. The device is configured so that the boiler feed water to the boiler on the right side of the boiler base and host for one, do not need to do another foundation. 3, the water cycle is simple, reasonable structure pressure parts, to ensure the quality of the situation, it is safe to run. 4, ancillary equipment, advanced comprehensive technical performance. Working Process boilers: Fuel from the outside air into the combustor through automatic adjustment, automatic ignition function generates high-temperature flame, the furnace front end into the burn chamber, the burnout chamber rear side into the convection heating surface, through the front smoke box the upper part of the convection heating surface into the second after leaving the boiler smoke box from the rear into the chimney into the atmosphere. Ruoyin tiaofeng inadequate settlement produce soot respectively the front and rear smoke box, burn indoors, open the inspection door can be fully cleaned. The working fluid through the heat generating saturated steam output from the main steam valve to the operating system. Auxiliary installation: ⑴, burner, feed water pump installation, the installation should be carried out in accordance with the supply list box to check, when confirmed physical and consistent supply list and passing the examination can be carried out after installation. After installation check for stuck air leakage and other shortcomings. The last power test to check motor rotation is normal, with or without friction vibration phenomenon, the motor temperature is normal. The smoke duct connection, if inconsistent with the design drawings, length, bend, large changes in cross-sectional area should be redesigned smoke wind resistance, proofreading drums, Fan's flow, pressure head, to meet the actual needs of the boiler. 5, install chimney: ⑴, between flanges should cushion when stone trapping Miansheng chimney installation and inspection methods hanging vertical chimney verticality. If error correction can be leveled at the flange connection. ⑵, cable (rope) tensioning flange bolts, pay attention to three of the tightness of the wire rope should be about the same. ⑶, in accordance with the requirements of the environment and the local authorities can be shortened or heightened stack height. 6, the boiler piping and instrumentation installation: a, normal water table and drum water level elevation deviation ± 2mm. It should accurately indicate the maximum safe level, marking the lowest security level and normal water level. b, water table should drain valve (or drain cock) and a discharge pipe connected to a place of safety. c, the pressure gauge should be installed to facilitate the observation and purge position and protect against high temperature, freezing and vibration impact. d, the pressure gauge should trap should be fitted between the pressure gauge and water in the faucet to purge the pipeline, for removable pressure gauge. shall be marked with the red line on the e, the dial face indicates the boiler operating pressure.
