what is boiler capacity?

posted:2019-05-23

   When a customer purchases a boiler, the determination of the boiler capacity is closely related to the customer's energy needs. Generally speaking, the output or capacity of the boiler should be determined according to the amount of steam used in the production process or the heating area and the heat required for domestic hot water. What is more, customers also need to know more about the boiler capacity. On the one hand, the determination of boiler capacity should have strong adaptability to changes in user load, and on the other hand, it should be conducive to saving manpower, material resources and infrastructure investment. So what is the boiler capacity?E3VIndustrial Steam Boiler

what is boiler capacity?E3VIndustrial Steam Boiler

  The capacity of the boiler, also known as the output of the boiler, is an indicator of the boiler's production capacity. It is the basic characteristic parameter of the boiler. There are many units for expressing boiler capacity, and a brief introduction will be made here.E3VIndustrial Steam Boiler

  Steam boilers are generally expressed in terms of evaporation, which refers to the quantity or capacity of steam produced per hour by the boiler, in tons per hour (t/h). The amount of boiler evaporation depends on the number of heated surfaces of the boiler and the combustion of the boiler. When the boiler is in operation, its combustion conditions are constantly changing and the amount of evaporation is constantly changing.E3VIndustrial Steam Boiler

  The capacity of the hot water boiler is expressed in terms of the amount of heat supplied by the boiler per hour, and its unit is megawatts (MW).E3VIndustrial Steam Boiler

  The boiler horsepower (Bhp or hp) is a unit of measurement of the boiler output, it is still very widely used in some countries. A Bhp is the amount of energy required to evaporate 34.5 lb / hr (15.7 kg / hr) of steam at atmospheric pressure and a temperature of 212 ℉(℃).E3VIndustrial Steam Boiler

  Steam boilers output can be expressed in btu or in pounds of steam delivered per hour. Large boiler capacities are often given in lbs of steam evaporated per hour (lbs/h)under specified steam conditions. Since the amount of steam delivered varies with temperature and pressure, a common expression of the boiler capacity is the heat transferred over time expressed as British Thermal Units per hour(btu/h). A boilers capacity is usually expressed as kBtu/hour (1000 Btu/hour).E3VIndustrial Steam Boiler
