How to determine correct firing rate on Steam Boiler — Heating …

Your radiation load =132,000 steam and about13,750 for the water for a total of 145,750 adding 1.15 for pick up=167,612. If you boiler efficiency is 80% you need a firing rate of 210,000. This would be a nozzle size of 1.50gph. This is reasonably accurate. Someone

The boiler is better able to respond to large loads as the 'low fire' position will ensure that there is more stored energy in the boiler. If the large load is applied when the burner is on 'low fire', it can immediately respond by increasing the firing rate to 'high fire', for example the purge cycle can be omitted.

A steam boiler or steam generator is a device used to create steam by applying heat energy to water. Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Boiler Efficiency - an overview | ScienceDirect Topics

Boiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler. Unburned carbon losses equate to the fraction of combustible fuel which is not burned in the boiler.
