Water Tube Natural Circulation D Type Boiler

Boiler circulation systems: natural circulation and forced

Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be …

Natural (or thermal) circulation boilers. Referring to figure-1(a), in the downcomer (pipe through which flow is directed downwards), no steam is present and the tube section A-B is not heated.Heat input generates a steam-water mixture in section B-C, usually referred to as riser (pipe through which flow is directed upwards).Due to the fact that the steam-water mixture at section B-C is less

D type watertube boiler design. D type watertube boilers are designed with a large steam drum at the top, vertically connected to a smaller water drum (or "mud drum") at the bottom, via multiple steam-generating tubes which carry feed water (providing the main heat transfer surfaces for the production of steam). These are surrounded by walls made up of larger water-filled tubes, which make up the furnace.
