efficiency difference between low high pressure boiler Agent


Engineering Chemistry: Lesson 11. Scale and sludge
(2) Lowering of boiler safety : Due to scale formation, over-heating of boiler is to be done in order to maintain a constant supply of steam. The over-heating of the boiler tube makes the boiler material softer and weaker and this causes distortion of boiler tube and makes the boiler unsafe to bear the pressure of the steam, especially in high-pressure boilers.

Absorption Refrigeration System - an overview
The absorbent (LiBr) acts as a refrigerant carrier from the low-pressure region to the high-pressure region of the machine. For water chilling, the COP of a LiBr–water ARS varies in the range 0.65–0.7. Heat input temperatures for single-stage machines are usually 95°C, whereas for two-stage ones they are approximately 150°C.

METHOD AND APPARATUS FOR INCORPORATING A LOW PRESSURE
Greater efficiency would be expected by mixing the helium with the compressed working fluid before heating in the boiler, but this presents problems, since the compressed working fluid is at a very high pressure, possibly in the range of 2000-4000 psig, while the helium is at a very low pressure, which makes mixing difficult.

High Pressure Boiler and Low Pressure Boiler--ZBG
The major difference between a low-pressure and a high-pressure boiler is the amount of pressure per square inch and pounds per square inch gauge that the boiler produces. In a low-pressure boiler the pressure does not exceed 15 psi, and hot water heating boilers are not designed to exceed over 260 psig. The temperature in a low-pressure boiler will not rise above 250 degrees F.
