WNS is a horizontal type gas boiler combustion three quick return fire tube boilers. Bias furnace using wet back structure, high temperature gas erosion followed the second and third return pipe tobacco, and then after the smoke from the chamber through the chimney into the atmosphere. Boiler fitted with removable front cover of smoke, easy maintenance of the boiler. Boilers with good technical performance burners, combustion using automatic ratio adjustment automatically adjusts the water supply, the program start and stop, automatic operation and other advanced technologies, and has low water level alarm and low water levels, 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 with quick factory condition. The product consists of three parts at the factory; boiler host, chimneys and piping systems, where the host and manufactured in the factory chimney section has been completed, the host supporting the pipeline valves, meters have been installed properly randomized, transported to the site will host and chimneys can be assembled. On-site gas supply is turned on, power supply, water pipeline to test. Greatly reducing the installation cycle, and can guarantee the quality of products. 2 design and advanced performance. The overall structure of the boiler host genus burner assembly on the front cover of smoke, the main body of the combustion chamber arrangement of heating surfaces and parts. With a reasonable structure, compact, low consumption of steel, furnace with a bias waveform furnace, insulation use of a new lightweight thermal insulation materials, packaging with color sheet, rectangular shape of the packaging for the boiler performance, weight, structure size , appearance and capacity of the domestic product compared with the obvious nature of beauty perception. The device is configured so that the boiler feed water in 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. Boiler work process: fuel by external gas source into the burner through automatic adjustment, automatic ignition function generates high-temperature flame, the furnace front end into the burn chamber on the rear side of the burn chamber into the convection heating surface, through the smoke box front upper body into the second convection heating surface after leaving the boiler from the back of the chimney smoke box into the atmosphere. Ruoyin tiaofeng inappropriate produce soot respectively the previous settlement, after the smoke box, burn indoors, open the door to check all the cleanup. Heat generated by the working fluid saturated steam output from the main steam valve to the operating system.
