Steam Boiler or Hot Water Boiler

posted:2016-11-07

Steam Boiler or Hot Water BoilerThe primary purpose of the industrial boiler is to supply energy to the facility's operations – for comfort heating, manufacturing process,hotel, central heating, etc. The nature of the facility's operation will dictate whether a steam boiler or hot water boiler should be used.M8oIndustrial Steam Boiler

What is hot water boiler used for?

Industrial Hot water boiler is commonly used in heating applications, with the horizontal boiler supplying water to the system at 120°F to 220°F. The operating pressure for hot water heating systems usually is 30 psig to 125 psig (hydro-static). Under these conditions, there is a wide range of industrial hot water boiler products available. If system requirements are for hot water of more than 250°F, a high-temperature water boiler should be considered. M8oIndustrial Steam Boiler

What is steam boiler used for?

Industrial steam boilers are designed for low-pressure or high-pressure applications. Low-pressure boilers are limited to 15 psig design, and are typically used for heating applications. High-pressure boilers are typically used for process loads and can have an operating pressure of 16 to more than 1,000 psig. Most steam boiler systems require saturated steam, which means the water and the steam in the vessel are at the same temperature. M8oIndustrial Steam Boiler

Industrial Steam and hot water boilers are defined according to design pressure and operating pressure. Design pressure is the maximum pressure used in the design of the boiler for the purpose of calculating the minimum permissible thickness or physical characteristics of the pressure vessel parts of the boiler. Typically, the safety valves are set at or below design pressure. Operating pressure is the pressure of the boiler at which it normally operates. The operating pressure usually is maintained at a suitable level below the setting of the pressure relieving valve to prevent their frequent opening during normal operation. M8oIndustrial Steam Boiler

Some steam applications may require super-heated steam. It should be noted that super-heated steam has a high enthalpy, so there is more energy per pound of steam and higher steam quality. One example of an application where super-heated steam may be required is with a steam turbine. The turbine's blades require very dry steam because the moisture can destroy the blades. When very high pressure or super-heated steam is required, an industrial water tube boiler should be selected. M8oIndustrial Steam Boiler
