5500 kg hr steam boiler, parameters for gas-fired steam boiler selection

Steam boiler refers to boiler equipment that produces steam. Water is heated in the drum to form steam. Steam boilers are pressurized boilers which belong to the special equipment, and are widely used in industrial production. When selecting a steam boiler, the customer needs to communicate the specific parameters of the steam boiler with the steam boiler manufacturer. In order to help customers find the appropriate equipment model, ZOZEN Boiler takes the 5500 kg hr steam boiler as an example to summarize the gas-fired steam boiler parameters as follows.

1.5500 kg hr steam boiler parameter: rated capacity

The rated capacity refers to the amount of steam produced per hour when the boiler adopts the designed fuel type and operates under the designed parameters (rated pressure, temperature, thermal efficiency) for a long time. When the new boiler leaves the factory, the rated capacity of this boiler will be indicated on the nameplate. The unit of rated capacity is t/h. Generally, the rated capacity of a 5500 kg hr steam boiler is 5.5 t/h.

2.5500 kg hr steam boiler parameter: rated steam pressure

The unit of pressure is Mpa. The rated steam pressure refers to the steam pressure at the outlet of main gas valve of the boiler superheater that must be guaranteed when the boiler operates under the designed thermal efficiency, steam temperature and feed water temperature for a long time. The rated steam pressure is often indicated on the nameplate of the boiler. For the boiler without superheater, it refers to the saturated steam pressure at the outlet of main gas valve.

3.5500 kg hr steam boiler parameter: steam temperature

The unit of steam temperature or superheated steam temperature is ℃. It refers to the temperature of steam at the outlet of the boiler. The steam temperature of the boiler depends on the pressure. If the boiler only produces saturated steam, only the steam pressure is required to be indicated on the nameplate; and if the boiler produces superheated steam, it is necessary to indicate both the steam pressure and temperature on the nameplate.

4.5500 kg hr steam boiler parameter: feed water temperature

The feed water temperature refers to the temperature of the water which enters the steam boiler as the working medium. The steam boiler parameter - rated feed water temperature is the feed water temperature that should be guaranteed within the specified range. ZOZEN gas-fired steam boilers are equipped with the economizer, condenser and other flue gas recovery devices, which can effectively use the high temperature of the flue gas to increase the return water temperature, so as to improve the thermal efficiency of the whole boiler system.

5.5500 kg hr steam boiler parameter: boiler thermal efficiency

The boiler thermal efficiency refers to the heat transfer effect of the heat generated by fuel combustion to the water in the boiler. The higher the thermal efficiency, the better the boiler performance. The thermal efficiency of gas-fired steam boilers produced by ZOZEN Boiler can reach 98%.

6.5500 kg hr steam boiler parameter: local exhaust gas emission limits

As the environmental protection policies become increasingly strict, the exhaust gas emission has become a decisive factor for the use of boiler, especially the NOx emission. The key areas require that the NOx emission of the boiler should not be more than 30 mg/Nm³, and some areas require that the value should not be more than 50 mg/Nm³.

The above is the common parameters of the 5500 kg hr steam boiler concluded by ZOZEN Boiler. If you have more questions about 5500 kg hr steam boiler, welcome to have an online chat with ZOZEN Boiler.
