Design parameters for boilers and hot water heating systems
Sep 21, 2021 · Condensing type boilers. Condensing type boilers have become more popular in the past 15 years. The combustion reaction within the boiler has a byproduct, CO 2 + H 2 O. This means that water must develop somewhere and water condenses in the boiler stack or flue due to the dew point temperature in the stack.

Types of boilers: Which one is the best? - Industrial
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.
