direct and indirect efficiency in boilers - energypurse

Direct and Indirect efficiency in boilers - EnergyPurse

Indirect efficiency is also known as heat loss efficiency calculation method. In this method, efficiency calculation is done by subtracting heat loss fraction from 100. Standard is ASME PTC-4-1 isused for calculating boiler efficiency by indirect method. The standards do not include blow down loss in the efficiency determination process.

High Efficiency and Standard Efficiency Boilers – Boiler

2020-1-30 · High efficiency boilers also take a little more heat from all of the gases passing out of the flue, and transfer it into the central heating water via the boiler heat exchanger. The flue gases from high efficiency boilers are therefore much cooler than those from standard efficiency boilers.
