Boiler Introduction: SZS boiler is called double cylinder longitudinal chamber combustion water tube boiler, cylinder outside the combustion chamber and heating surface, so that water and steam flow in the tube of industrial boiler. Compared with the boiler shell boiler (WNS boiler), the SZS series oil/gas steam boiler drum diameter is smaller, the working pressure is large, the water capacity is small, once the accident occurs, the disaster is lighter. At the same time, the water circulation of the SZS series oil/gas steam boiler is good, the evaporation efficiency is high, the ability to adapt to the load change is better, and the thermal efficiency has also been improved.
SZS Series Steam Boiler Description
SZS series boiler is designed with longitudinal double drums and ” D ” type chamber structure. Furnace is placed on the right and convection tube bank is on the left, super heater is arranged at convection tube bank. The body is fixed on the basement by middle and both end flexible supports and make the boiler expand horizontally sideways. Around the furnace is membrane water cooling tube wall. Furnace and tube bank are totally separated by the membrane water tube cooling wall at the left side of the furnace. The back part of bundle is sparse shift structure, front part is aligned structure. Smoke from furnace outlet enters re-burning chamber, convection tube bank area and then from left front part enters spiral fine coil economizer and condenser, and finally is discharged to atmosphere through chimney.
Oil/Gas Steam Boiler Characteristics
- Full membrane type water wall structure: boiler body sealing is reliable, prevent flue gas leakage;
- High efficiency heat exchange element: add energy saving device, condensing heat exchange is more sufficient, improve heat exchange efficiency, lower smoke exhaust temperature;
- A wide range of fuel: natural gas, liquefied petroleum gas, urban gas, methane, etc., to meet the requirements of burning multiple fuels;
- Safe water circulation: compound water circulation structure, the heating surface design water speed safety, with superior power failure protection function;
- Quick start and stop: the use of high thermal resistance light material furnace wall, good thermal insulation performance, small heat loss;
- Low nitrogen environmental protection: SOX ≤5mg, NOX ≤30mg, the pollutant indicators are far below the specified emission standards;
- Low operation cost: micro-positive pressure operation, low power consumption without induced draft fan, overload capacity, easy maintenance, greatly reduced cost;
- Less investment in boiler room: the total weight of the boiler is only 1/2 of the same capacity of the coal furnace, reducing the load-bearing load of the foundation and reducing the cost of the boiler room.
SZS Series Steam Boiler Details
- Good quality of boiler: more than 95% automatic welding equipment, each boiler before leaving the factory are testing and quenching treatment, to ensure that the inspection pass rate of 100%.
- Good heat transfer performance: the drum is not directly heated, and the heat transfer and safety performance have been significantly improved by placing the pipe to accommodate water vapor in the furnace and flue as the heating surface.
- High matching degree of burners: the use of world famous brands of burners and gas valve sets and other auxiliary machines and components, from the filter, pressure regulating valve, solenoid valve and other complete gas valve sets and accessories, to ensure the safety of gas, and the operation of the boiler is always in the best combustion state.
- High thermal efficiency: a large number of heat transfer pipes are arranged in the furnace body, with large heat transfer area and high thermal efficiency, thus saving a lot of fuel costs.
