What parameters do I need to know when choosing a steam boiler?
The steam boiler mainly has the following parameters:

1.Rated evaporation

The rated evaporation is the power of the steam boiler, which is the most important parameter of the steam boiler. It is generally expressed in tons of evaporation, which is how many tons of boilers we usually say.

2.Rated steam pressure

The rated steam pressure refers to the steam pressure generated in the steam boiler, which is generally expressed in MPa or kg. 1 MPa is 10 kg. Generally, low-pressure steam below 1.0 MPa is used in conventional steam applications such as laundry rooms, hospitals, and factories. High-pressure steam is required only when steam is used as power.

3.Steam temperature

The steam temperature mentioned here refers to the temperature of saturated steam. The temperature of the saturated steam corresponds to the pressure of the steam. The saturated steam temperature at a pressure of 1 MPa is 184 ° C.

4.Gas / fuel / coal consumption

Fuel consumption is an important indicator to pay attention to when purchasing a steam boiler, and it is directly related to the operating cost of the boiler. In the operation of the boiler, the fuel cost is considerable. If you consider the purchase cost to buy a cheap but high energy consumption boiler, which will lead to high operating costs in the later period, you will definitely lose more than you get.

5.Boiler thermal efficiency

The thermal efficiency of a boiler is inversely proportional to the fuel consumption of the boiler. The higher the thermal efficiency, the lower the fuel consumption of the boiler. The thermal efficiency of a boiler is expressed as a percentage, which is a relatively intuitive value.

6.Operating weight and overall dimensions of the boiler

When choosing a steam boiler location, you should check whether the unit area bearing capacity of the location can bear the weight of the steam boiler, and whether there is enough space to place the steam boiler and space for maintenance.
