standard indirect boiler principle

Direct and Indirect efficiency in boilers

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. Boiler indirect Efficiency = 100 (i +ii + iii + iv + v + vi + vii) Where i.

The indirect-fired water heater does not itself turn on the heating boiler. Rather when temperatures inside the separate heating boiler drop below a low limit (or hot water maintenance level) set on the heating boiler's own control that system will turn on its burner to re-heat the boiler water directly.
