The term boiler is applied to the single heat source that can supply either steam or hot water (a boiler is often called a heater). Boilers may be classified according to several kinds of characteristics. They are typically made from cast iron or steel. Their construction design may be sectional, portable, fire-tube, water-tube, or special.Get Price

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low …Get Price
Typical design temperature required is 120 F. to 180 F. 6) Embedded Floor Heating. A piping system embedded in a concrete floor such as a basement, garage, or workshop. A floor covered with a topping pour of gyp-crete or concrete would also fall into this category. Typical design temperature required is 80 F. to 130 F. 7) Snow Melt.Get Price
the air preheater is to recover the heat from the boiler flue gas which increases the thermal efficiency of the boiler by reducing the useful heat lost in the flue gas. As a consequence, the flue gases are also conveyed to the flue gas stack (or chimney) at a lower temperature, allowing simplified design of the conveyance systemGet Price
To maintain boiler integrity and performance and to provide steam of suitable turbine or process purity, boiler feedwater must be purified and chemically conditioned. The amount and nature of feedwater impurities that can be accommodated depend on boiler operating pressure, boiler design, steam purity requirements, type of boiler water internal treatment, blowdown rate, and …Get Price

Boiler design. Contemporary boilers are significantly smaller than their counterparts of only 30 years ago. At best, the steam produced is wet and contaminated. This, coupled with a reduction in pressure, can lead to: A line-size check valve is required to prevent reverse flow of the steam back to the boiler in the event of the boiler Get Price
Jul 29, 2021 · Formerly the Cochran Borderer steam boiler utilises a full wet back design for maximum efficiency. A key feature of the ST25 series is the boilers' compact design.
