Updated on June 30, 2019 Before the eighteenth century, Britain — and the rest of Europe — had produced coal, but only in a limited quantity. Coal pits were small, and half were opencast mines (just big holes in the surface). Their market was just the local area, and their businesses were localized, usually just the sideline of a larger estate.

Since coal can heat much larger volumes of water much faster than wood, coaldriven steam engines can be much larger than wood steam engines. Coal beats wood. Oil beats coal. Dense with energy, oil provides 18,300 BTU/lb. And rather than needing to be shoveled or tossed, it can be pumped through pipes.

Condenser. Condenser is a device which condenses the exhausted steam from the turbine. The condenser serves two important functions −. It creates a very low pressure at the exhaust of the turbine, hence permitting expansion of steam in the turbine to a very low pressure. This helps in converting the steam energy into the mechanical energy.

Merchants built factories that needed water power that had to be built near water. People learned they could burn coal to make hot water for steam power. In 1769, James Watt built a good steam engine. The steam engines were being used to run machines in factories instead of water power. Now factories could be built farther away from water sources.
