WNS Condensing Gas Fired Steam Boiler

 The gas-fired steam boiler adopts a horizontal internal combustion two-pass wet-back structure. The corrugated combined furnace is one return, and the second return is composed of threaded smoke tubes. The back tube plate of the boiler is not directly washed by high-temperature flue gas, and the working conditions are improved.

  1. Rated steam pressure: 1.25MPa
  2. Rated steam temperature: 194
  3. Applicable fuel: natural gas, heavy oil, light oil, coal gas
  4. Scope of application: chemical, plastic, rubber, Jianye, forestry, pharmaceutical industry distillation, etc.



The condensing gas steam boiler adopts a bottom furnace, a corrugated furnace, and a two-pass flue gas condensing design. The smoke and dust emission meets the national environmental protection requirements. The furnace chamber adopts corrugated furnace, which greatly improves the heating surface and strength.

The gas-fired steam boiler has a reasonable and compact structure, strong load adaptability, complete combustion and high thermal efficiency. This series of boiler products have large heating area, fast heating and pressure rise, and easy operation. The body safety accessories are complete to ensure safe and economical operation. Equipped with high-quality burners, the combustion is stable and reliable.

The WNS series steam boiler adopts a horizontal internal combustion two-pass wet back structure. The wave-shaped combined furnace bladder is the first return stroke, and the second return stroke is composed of a threaded smoke tube. The back tube plate of the boiler is not directly washed by high-temperature flue gas, and the working conditions are improved. At the same time, this structure greatly reduces the heat dissipation loss at the rear of the boiler. In order to improve thermal efficiency, an economizer and condenser are arranged in sequence at the outlet of the front smoke box of this type of boiler, which has a significant energy saving effect.



This type of gas fired boiler has high and low water level alarm functions, low water level interlock protection functions and overpressure interlock protection functions. In order to effectively monitor and control the water level and pressure, the boiler is equipped with a water level gauge, an electrode type water level control alarm, a pressure gauge and a pressure controller, so that the boiler has high and low water level alarms/low water level interlock protection and steam Pressure overpressure interlocking protection, boiler automatic ignition, automatic burner power adjustment and flameout protection ensure the safe operation of the boiler.

Parameters and technical requirements of 6-ton gas-fired steam boiler for hospital use

 The 6ton gas-fired steam boiler is commonly used in hospitals, and its process requirements are as follows: Natural gas boiler: natural gas → burner → boiler → steam → sub-cylinder → steam point. Tap water constant pressure water supply → water softener → soft water insulation water tank → energy saver → boiler. Hospitals are densely populated places, so the requirements for boiler equipment and suppliers are relatively strict. Suppliers of 6ton gas boilers must have a Class A boiler manufacturing license, a pressure vessel manufacturing license, a Class 2 boiler installation, renovation and maintenance license or above. The equipment supplier shall be responsible for obtaining relevant certificates and fees such as the registration certificate for installation and use of boiler equipment. The water supply of this series of gas boilers is designed with a flue gas condensation recovery device to recover the heat energy of the flue gas, and the exhaust gas temperature is less than...

SZS Gas-Fired Horizontal Water-Tube Saturated Steam Boiler

 The pipelines within the scope of the SZS watertube steam boiler only include the valves and pipelines from the flange of the return water check valve to the outlet valve and drain valve of the boiler body. Accessories include valves and gauges for the boiler body. Such as pressure gauges, air valves, spring safety valves, outlet and return valves, check valves, thermometers, etc. The SZS gas-fired steam boiler is equipped with a flue gas condenser at the tail of the boiler body, which reduces the flue gas temperature (<70°C), improves the boiler efficiency and reduces the harmful components in the flue gas. The boiler adopts micro-positive pressure combustion, and the furnace wall tube is a full-membrane wall structure. This series of boiler products has a certain pressure bearing capacity, and no smoke leakage and air leakage will occur when running under a slightly positive pressure state. The boiler is a self-contained boiler, which can shorten the installation period whi...

35 Tons SZS Gas Steam Boiler

 The SZS gas fired steam boiler is equipped with a flue gas condenser at the tail of the boiler body, which reduces the temperature of the flue gas, improves the efficiency of the boiler, and reduces the harmful components in the flue gas. The szs gas boiler adopts micro-positive pressure combustion, and the furnace wall tube is a full-membrane wall structure. The 35ton gas-fired boiler has a certain pressure-bearing capacity, and there will be no smoke leakage and air leakage when running under a slightly positive pressure state. The boiler is a self-contained boiler, which can shorten the installation period while meeting the transportation size requirements. At the same time, the aluminum casing and the skeleton are transported and connected by bolts, which are convenient for disassembly and maintenance. The furnace of this series of boiler products adopts a model water-cooled wall structure, and the whole boiler adopts an air-tight inner shield with a fully enclosed welding s...
