Water Tube Boiler - Definition, Components, Working

The water tube boiler diagram is shown below, and these two drums are associated via two tubes such as downcomer and riser. At first, the water is supplied into the steam type drum with the help of a water pump. Whenever the fuel is burned, then hot gases will be generated that are permitted to supply in the shell part of the boiler.

VISITING BOILER PENTHOUSES & BOILER ROOFS

See photograph 1 & 2. This was an AFBC boiler with unfinned waterwall design. The roof seal work was made of refractory tile followed by castable refractory. The boiler was lignite fired. The complaint in this boiler was the poor combustion efficiency. With air ingress through the cracks in refractory roof, how could any one follow the oxygen?
