[PDF]Classification of boilers – High-pressure boilers are boilers operating at a steam or other vapor pressure in excess of 15 psig, or a water or other liquid boiler in which the pressure exceeds 160 psig, or has a temperature greater than 250 degrees Fahrenheit. Others are low-pressure boilers. License requirement

7) Low pressures Condensate (LC). BOILER FEED WATER; 1) High pressure boiler feed water (HP) 2) Medium pressure boiler feed water (MP) 3) Low pressure boiler feed water (LP) Following conditions should be fulfilled to follow IBR norms. 1) < 3.5-kg/cm2 IBR approval is not required.

A high pressure boiler plant of 51 to 500 horsepower is exempt from the high pressure attendance requirements of item A if the plant is operated at low pressure. All boilers must either be shut down or shifted to low pressure. If a boiler is shifted to low pressure, it must have the following controls, safety devices, and conditions: §

File Size: 272KB This procedure defines the requirement and procedure of hydrostatic testing of the boiler pressure parts after completing the assembly of all the boiler high pressure and temperature components. Hydrostatic testing Objective Hydrostatic testing in the boiler is carried out to check the following: Leakages in the boiler pressure parts (Tubes, headers and Pipes).

Types of High Pressure Boilers. A boiler is a vessel in which water is heated under pressure and vaporized into steam for a specific purpose. There are several different kinds of boilers, heated by coal, solid fuel, oil or gas. Boilers vary widely in size from small, portable or shop-assembled units to large furnaces

5) The boiler will automatically stop at the set pressure by the high steam pressure switch. 6) Min valve should be opened slowly so that pressure does not drop below 5 Kg/cm because it is low-pressure safety.

File Size: 372KB [PDF](c) "Low pressure boiler" means a boiler in which steam or other vapor is generated at a pressure of not more than 15 psig or water is heated to a temperature not greater than 250°F and a pressure not greater than 160 psig, including the following:

Over time, boilers under stress from high pressure are likely to develop cracks and seal breaks in valves and pipework causing leaks. Unfortunately, you’re at the very least going to need these parts replaced – and in most cases, it’s going to be more economical to invest in a new boiler.
