DZL series steam boiler with high efficiency heat transfer components, cylinder screw smoke pipe reasonable layout, heating surface and combustion device layout is reasonable, so that the boiler thermal efficiency is 4-8 percentage points higher than the specified standard, quality, reliable. Coal fired boilers supply with reasonable smoke speed design, heating surface no dust, no wear. Can maintain high efficiency for a long time, full load state for safe operation.
Coal fired steam boiler adopts a number of advanced production technology, high degree of mechanization and automation. The arch tube plate and threaded smoke pipe can make the pot shell change from quasi-rigid body to quasi-elastic body. With the airfoil flue, the disadvantages of cracking of the traditional high temperature tube plate of boiler can be completely avoided. Reasonable water circulation circuit and unique backwater ejector device are set in this series of boilers, which can improve the water speed of rising pipe and avoid the phenomenon of water wall burst pipe.
Coal fired boilers supply with energy-saving, strong radiation furnace arch, stable combustion, fuel saving. It can also adopt inertia separation of smoke and dust in the furnace, and cooperate with efficient dust collector, so that smoke and dust discharge can meet the stipulated environmental protection requirements. The coal fired boiler is compact in overall structure and reasonable in design. The screwed pyrotechnics tube is arranged in the boiler drum to form the convection heating surface. The boiler drum and the water wall on both sides to form the radiant heating surface of the furnace chamber. Combustion equipment using light chain grate; Whole quick packing form factory. Electric control grate stepless speed regulation, limit parameter alarm and interlock protection
DZL series of coal fired steam boilers adopt advanced numerical control machining, such as steel plate blanking, ring, drum, tube plate drilling, etc., to reduce the assembly stress and extend the service life of the boilers. Steel pipe cutting, screw pipe pressing, convection pipe processing all adopt advanced numerical control technology. Adopt arch tube plate and screw pipe structure, increase heat conduction, completely solve the crack problem of the back tube plate. Set up chain grate, front and rear smoke box panels are cut by numerical control plasma cutting machine, neat and beautiful.
Coal fired boilers supply manufacturing technology advanced, using automatic spinning line operation. Enhance heat transfer and improve boiler thermal efficiency. The screw pipe is a high efficient heat transfer element researched by our company for many years. After continuous optimization, it can meet the minimum flow resistance and the heat transfer coefficient is higher than that of ordinary pipe. Zozen Boilers specialize in producing high quality boiler products, has been devoted to producing high quality boiler products of various types for many years, now our Boilers have been sold to more than 100 countries and regions all over the world, providing a full set of high quality boiler service to many users, welcome to consult and cooperate with us.
