Brief Description of WNS2-1.0-YQ 2 Ton Low Nitrogen Steam Boiler

 The 2ton low-nitrogen steam boiler adopts a large furnace and corrugated furnace structure, which increases the radiation heat transfer area and facilitates the full combustion of fuel. Applying fuzzy control technology based on artificial neural network and world-famous burners to realize automatic adjustment of combustion according to temperature, pressure and time, so that the boiler can operate efficiently and economically under different conditions, and minimize fuel consumption.



The low-nitrogen steam boiler adopts low-NOX combustion technology to optimize the boiler structure design, and automatically adjusts the boiler combustion conditions through flue gas detection, thus ensuring that the boiler flue gas emission meets the requirements of environmental protection in my country and the world, and has low operating noise.

The front and rear smoke boxes of this series of steam boilers adopt a movable double-sealed structure, which is convenient for inspection, maintenance and cleaning of the inside of the boiler. The boiler is integrated quickly, runs without vibration, and is convenient and quick to install. The boiler computer controller can automatically record the time and time of the failure. The reason is convenient for maintenance personnel to perform maintenance.

The boiler adopts a flue gas condensing waste heat recovery device, and uses lower temperature water or air to cool the flue gas to reduce the flue gas temperature. Close to the heat exchange surface area, the water vapor in the flue gas condenses, and the flue gas sensible heat release and water vapor are realized at the same time The latent heat of condensation is released, and the water or air in the heat exchanger absorbs heat to be heated, which realizes heat energy recovery and improves the thermal efficiency of the boiler.



The thermal efficiency of WNS type boiler is improved: 1NM3 natural gas combustion produces about 10.3 NM3 (about 12.5KG) of theoretical flue gas. Taking the excess air coefficient of 1.3 as an example, 14 NM3 (approximately 16.6KG) of flue gas is produced. When the temperature of the flue gas is reduced from 200°C to 70°C, the physical sensible heat is about 1600KJ, the water vapor condensation rate is 50%, and the latent heat of vaporization is about 1850 KJ. The total heat release is 3450 KJ, which is about 10% of the low calorific value of natural gas. If 80% of the flue gas is taken into the thermal energy recovery device, the thermal energy utilization rate can be increased by more than 8%, and the natural gas fuel can be saved by nearly 10%.

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...
