Their construction design may be sectional, portable, fire-tube, water-tube, or special. Domestic heating boilers are generally of low-pressure type with a maximum working pressure of 15 pounds per square inch (psi) for steam and 30 psi for hot water. All boilers have a combustion chamber for burning fuel.Get Price
Dec 01, 2016 · The manufacturer's rating for boilers indicated a boiler efficiency of 0. 7 with LP gas and 0.78 with natural gas. The value of 0.58 was used in calculating the needed boiler capacity due to intermittent and low-load operation. A boiler with a rated input value of 66,000 Btu/hr (19.5 kW) was selected for the Penn State digester installation.Get Price

High-temperature hot water boilers operate at pressures of up to 500 psig, although the usual range is 35-350 psig. System pressure must be maintained above the saturation pressure of the heated water to maintain a liquid state. The most common way to do this is to pressurize the system with nitrogen.Get Price
Feb 21, 2016 · Super-Critical Boilers and Ultra-Supercritical Boilers operate at temperature and pressure higher than regular boilers. By operating at higher temperature these systems become more efficient. Super Critical Boilers typically have 10%-20% CO 2 emissions than other similar sub-critical technologies.Get Price
There are basically two types of boilers: Fire tube boiler Water tube boiler Fire tube boiler The name fire tube is very descriptive. The fire, or hot flue gases from the burner, is channeled through tubes that are surrounded by the fluid to be heated. The body of the boiler is the pressure vessel and contains the fluid.Get Price
