The capacity of industrial boilers

ZOZEN BOILER
Generally, industrial boilers are divided into steam boilers and hot water boilers. Boilers that produce steam are called steam boilers, mainly used to provide steam for industrial uses; Boilers that provide hot water are called hot water boilers, mainly used for industrial and central heating. Both the two types of boilers can use capacity to indicate the ability of heat supply, which is a direct standard for boiler capacity evaluation.

The unit of the capacity of industrial boilers
ZOZEN BOILER

Tons per Hour (t/h) is an engineering term, also known as boiler capacity, boiler output, etc. It refers to the amount of steam generated per hour by a boiler at a certain pressure and temperature. Generally speaking, a 1tph boiler means that a boiler can produce one ton of steam per hour rather than the physical weight of the boiler is one ton.

Megawatt (MW) is a unit of thermal measurement. It is used to indicate the heat amount produced per hour by a hot water boiler at a certain pressure and temperature, commonly known as boiler output. The heat output of a 0.7MW hot water boiler per hour is equivalent to the heat of 1 ton of steam.

Boiler horsepower (Bhp) is a non-public braking force measurement unit used to measure the power of steam boilers during 19th to the 20th century. The general definition of a BHP means the energy required to produce 34.5 pounds (15.65 kg) of steam at the pressure of 0 psig (0 bar) and the pressure of 212°F (100°C) per hour.

Capacity classifications of industrial boilers

Industrial boilers have many structural forms. The parameters differ according to different uses. So far, there has not been a unified rule. According to the different capacities, industrial boilers can be divided into three categories: small boilers, medium boilers and large boilers.

Selections of the capacity of industrial boilers

The capacity of industrial boilers should be determined according to the actual steam consumption or the area of heating supply.
First of all, you need to know the overall load range. Secondly, you need to find out the the peak conditions, including the duration of peak load, the frequency of peaks, that is, the periodicity of peaks. After having a thorough understanding the total load demand and peaks, you can consider the selection of the boiler capacity and boiler numbers. It is also necessary to consider the reserve amount while selecting boilers.
