Thermal Design of Economizer for Waste Heat Recovery Boiler
waste heat recovery boiler and that waste heat is taken from coke oven batteries. Waste heat recovery boiler uses waste flue gases for steam production, so this economizer is also work on these varying parameters like gas flow rate, content in flue gases.

Heat pumps vs Gas boilers — MoneySavingExpert Forum
2021/10/19 · Gas storage isn't going to reduce emissions though, nor are feed in tariffs. We do need to minimise consumption, which is why heat pumps are a jolly good idea. It's just that they're not financially viable for the average home whilst gas is still available and they're not insulated and airtight enough. They just don't reach temperature high

What are Boilers and Their Types? - Engineering Choice
Fire-tube boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. Fire-tube boilers, typically have a lower initial cost, are more fuel-efficient, and are easier to operate. Their capacities are up to 25tons/hr and 17.5 kg/ cm2.

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.

Heat Pumps – Analysis - IEA
In 2020, electric heat pumps still met no more than 7% of heating needs in buildings globally, yet they could easily supply more than 90% of global space and water heating at a lower CO 2 emissions level – even taking the upstream carbon intensity of electricity into account – than condensing gas boiler technology (which typically operates at 92-95% efficiency).
