SZS type gas-fired boiler adopts two leading technologies in the field of low nitrogen combustion in the world: graded combustion and FGR flue gas recycling, which can reduce the emission of NOX to less than 26 mg/m3. Gas steam boiler performance in full compliance with the current most stringent low nitrogen emission standards (30 mg/m3). It has reached the advanced level of low nitrogen emission combustion technology. Combined with the high safety of SZS type boiler, the thermal efficiency of up to 98%, and the equipped intelligent boiler Internet of things system, the boiler type not only achieves ultra-low nitrogen emissions, but also greatly saves energy, and has become the customer’s priority choice.
This series of gas-fired boilers are applicable to a wide range of fuels, and can be used for high, medium and low calorific value gas fuels. Flexible arrangement, various parameters (saturation, overheating). Complex manufacturing, long installation cycle. The performance of the boiler is not only related to the quality of manufacture, but also to the quality of installation. SZS series steam boiler adopts double cylinder longitudinal type “D” type layout quick installation water tube boiler, compact structure, small footprint, good flame filling degree. The steam boiler furnace adopts the pattern of water wall structure, the boiler as a whole adopts the closed welding structure of the air tightness inside the guard plate, the furnace wall sealing is good. Adopt automatic burner, water supply adopts continuous electric regulation, high combustion efficiency. And has multiple protection functions, safe and reliable operation.
Gas steam boiler performance is reliable, the boiler is arranged with explosion-proof door and flame detector, safe and reliable operation. This series of boiler products adopt forced circulation in the high temperature area to ensure that the heating surface of each part can be cooled reliably and prevent vaporization. The sealing between the membrane wall and the drum on both sides of the boiler adopts the comb plate, which eliminates the problem of condensate water and gas leakage caused by the sealing with refractory concrete. Zozen Boilers each boiler is inspected for gas tightness before leaving the factory to ensure no slight gas leakage.
SZS series steam boiler flue and boiler flue gas orifice with internal insulation measures, effectively reduce the noise of the boiler operation. The combustor adopts full film type water wall structure, adopts micro positive pressure combustion, no smoke problem, no pollution in operation environment. This series of steam boiler adopts high quality aluminum silicate fiber, and then use refractory mud insulation, furnace body temperature control below 45℃, effective control of heat loss. Boiler combustor adopts narrow spacing tube film type water wall, has good air tightness, reduce heat loss, improve the function of boiler thermal efficiency.
The gas steam boiler performance is reliable. The front and rear walls of the boiler are all membrane structure, which greatly improves the service life of the front and rear walls. Forming high aluminum refractories and manhole cover sealing device are used in the observation hole of boiler, which changes the problem of overheating caused by building with firebrick. Anti-chatter fasteners are adopted in all the convection tubes in the high temperature area of gas boilers, which eliminates the fracture of the convective tube bundle.
