3.Two types of high pressure water tube boilers are specified, flex tube and D-type. The two boiler types are significantly different, and only one of the two types should typically be specified if all new boilers in a given project are similar. 4.Flex tube boilers: a)Primarily for non-critical service firing gas fuel and with stable steam demands.

Vertical cylindrical hot water boilers. In the vertical hot water boilers the flue gasses initially flow downwards through a radiation section. The flue gasses are reversed into vertical pipes when they reach the bottom of the boiler. Due to the vertical orientation the soot blowers clean the pipes more efficiently.
