Aluminum silicate felt and superfine glass silk wool are used as insulation materials for low nitrogen water tube boiler. The total thickness of about 200mm, two kinds of insulation layer for air interlayer. This thermal insulation makes the heat loss of the boiler to a minimum, thermal efficiency is greatly improved, fuel saving, low operating costs. Low nitrogen steam boilers condenser not only absorbs a lot of sensible heat in the flue gas, but also absorbs a lot of latent heat in the flue gas. The efficiency of the boiler is higher than that of the ordinary boiler, and the condensing waste heat recovery device adopts special acid resistant, chloride ion corrosion ND steel, greatly prolongs the service life of the boiler.
Water tube steam boiler uses micro positive pressure combustion, furnace wall tube is membrane wall structure. It has a certain pressure bearing capacity, and no smoke leakage and air leakage will occur in the operation under slightly positive pressure. This series of boiler products is double drum horizontal type, water capacity is small, gas (oil) as fuel, the heat storage in the furnace is very small. After power failure, the water vaporization rate is low, which makes power failure protection easy to operate. The boiler is equipped with explosion-proof door and furnace pressure monitoring device to ensure safe and reliable operation.
Low nitrogen steam boilers is arranged before and after the boiler barrel manhole device, the rear of the furnace and flue are arranged on the inspection door, convenient maintenance. SZS series steam boiler for the complete boiler, in order to meet the requirements of transportation size at the same time, shorten the installation cycle. At the same time, aluminum outsourcing is connected with the skeleton by bolts, which is convenient for disassembly and maintenance. The boiler combustion process is mainly fixed on the front wall by the burner, after the fuel is ejected by the burner, in the furnace chamber (first return) micro positive pressure combustion. After radiation and heat release, the high temperature flue gas will turn 180° to the left after the furnace and enter the convection tube bundle of the second return journey and flow to the front of the furnace. In front of the furnace, it will turn 180° to the left and enter the energy saver or condenser (the third return journey) and fully exchange heat with the finned tube. Finally, it will enter the chimney and discharge into the atmosphere through the flue.
This type of steam boiler selects the famous brand burner with superior performance, and burns efficiently. Reduce mechanical incomplete combustion loss, chemical incomplete combustion loss, realize low oxygen combustion, reduce excess air, reduce exhaust temperature as much as possible, reduce exhaust heat loss, improve the thermal efficiency of the boiler, save operating costs to the maximum extent. Low nitrogen water tube boiler has a powerful automatic control system, the company has the boiler industry’s best automatic control technology ability, the use of automatic combustion proportional regulation, three impulse water supply automatic regulation system. Program start and stop, automatic operation and other advanced technology, and with high and low water level alarm and extremely low water level, ultra-high steam pressure, flameout, gas leakage and other automatic protection functions, to ensure the safe and stable operation of boiler equipment.
The low nitrogen steam boilers adopts a threaded smoke tube with a high heat transfer coefficient to enhance the convective heat transfer effect. It can reduce the exhaust gas temperature and improve the thermal efficiency of the boiler. The design of the rear view device of the steam boiler makes it easy to observe the combustion status. SZS series steam boiler furnace adopts membrane type water-cooled wall structure, and the whole boiler adopts air-tight inner protective plate of fully enclosed welding structure, which has good sealing performance of the furnace wall; low exhaust gas loss and high thermal efficiency. The boiler products produced by Zozen Boilers have good environmental performance, sufficient boiler output and overload capacity. Welcome everyone to consult and purchase!
