Firstly, what is Heat Rate?? gt; Any measurable parameter which has "Rate" ### Boiler Efficiency — What Gross and Net Efficiency Mean

The gross heat energy (total heat) from the combustion gases has two components; about 90% is sensible heat (heat which can be sensed or felt) and about 10% is latent heat. Latent heat is the energy which keeps the water vapour (produced by combustion) in a vapour state so that it passes out of the flue and doesn't all condense inside the boiler. ### How Can Plant Maintenance Improve Heat Rate and

Improving Heat Rate through Plant Maintenance. Heat rate is a metric that measures how much heat energy is required to produce a unit of work, frequently 1 kW. It is expressed in Btu/kWh. You can take heat rate and find thermal efficiency by dividing 3,412 by the heat rate and multiplying by ### How do you calculate boiler heat rate - Answers
