In a firetube boiler, the high temperature flue gas produced by the burner flows through a threaded pipe surrounded by water to heat a mixture of water, steam or soda outside the pipe wall, producing steam or hot water. Gas fire tube boiler drilling precision is high, high temperature area, smoke box and other key parts of the expansion process. Zozen Boilers has specially introduced CNC high-speed plane drill and a complete set of German milling cutter for tubeplate processing, which greatly improves the machining accuracy of tube hole and the surface smoothness of hole, creating good conditions for subsequent processing technology such as tube expansion. The tubesheet raw material is made of customized steel plate. Whether it is 6 tons or 20 tons, it is made by stamping the whole steel plate. There is no jointing process, so the manufacturing cost is lower.
Natural gas boiler adopts wet-back three-return structure, symmetrical arrangement of smoke pipe, uniform distribution, can improve the stress distribution of tube plate. The wet-back structure combustors are completely immersed in water, with good cooling conditions and long service life. The application of corrugated furnace liner not only increases the heating surface but also relieves the damage caused by thermal expansion and contraction to the combustion chamber and improves the intensity. The front and rear smoke boxes are hinged for easy opening and maintenance. Large steam space makes the steam out of the water speed is low, and the built-in soda water separation device, to ensure stable steam output.
The gas fire tube boiler adopts threaded smoke tube to enhance the heat exchange effect and improve the thermal efficiency. The series of boiler products using digital control technology, remote control combustion process. High degree of automation, all kinds of protection perfect, to achieve automatic control of water level pressure. The condensation heat exchanger made of special material can be added to the smoke outlet to reduce the smoke exhaust temperature and collect the sensible heat and latent heat in the flue gas, and improve the efficiency of the boiler (up to 95). The flue has a bypass flue, which can be adjusted according to the size of the boiler load to adjust whether to put into the use of the condenser.
Natural gas boilers are widely used in chemical industry, power generation industry, pharmaceutical industry, wine industry, heating industry, paper industry, food industry, textile industry, rubber industry, tobacco industry, non-ferrous metal industry, building materials industry, feed industry and so on. This series gas fired boiler is a kind of automatic, safe and efficient heating equipment. Gas-fired boilers have compact structure, small volume, strong load adaptability and low water quality requirements. This type of boiler load regulation, automatic water supply and other automatic operations, to meet the requirements of users. It has the advantages of high efficiency, energy saving, large steam space, safety and reliability, simple operation, longevity and durability.
WNS series gas boiler adopts finned economizer and condensing heat exchanger, which effectively reduces the exhaust temperature. Condensing energy saving device In order to prevent acid corrosion of exhaust condensate, the use of SUS304 or ND material steel made of finned tube. Compared with the light tube, its heat transfer efficiency is more than 2 times higher than the straight tube. The gas fire tube boiler adopts frequency conversion continuous water supply control to save 40% electric energy. The boiler uses proportional control combustion technology to save 5% fuel and reduce operating noise. The harmful gases in the flue gas are effectively controlled and flow into the neutralization tank with the condensate. Boiler water inlet system manufacturer unified configuration, simple, beautiful, saving installation costs.
