What is a Steam Boiler? Working, Types of Heat …

It is a fire tube, horizontal, internally fired, and natural circulation boiler, stationary and low-pressure boiler. Since it is a low-pressure boiler steam production will be less. Due to the lower steam production, the efficiency of the boiler is also low compared to the water tube boiler. The Lancashire boiler is shown in the figure below.
