⚙️ Process
Step-by-Step Working of a Lancashire Boiler
Follow the path of heat and water.
The brickwork setting (the surrounding brick structure) forms the bottom and side flues, ensuring maximum heat extraction before gases escape to the chimney.
↳ The working involves coal combustion, hot gas flow through flues, and heat transfer to water, producing steam.
