Generating steam using water tube boilers. The differences between a fire tube boiler and a water tube boiler are fairly straightforward. In a water tube boiler, the water is contained within the tubes, and the air heats the water from outside. Usually, some of the water tubes also form the walls of the furnace.
6. Heat loss due to radiation and convection: Normally surface loss and other unaccounted losses is assumed based on the type and size of the boiler as given below- • For industrial fire tube / packaged boiler = 1.5 to 2.5% • For industrial water tube boiler = 2 to 3% • For power station boiler = 0.4 to 1% 24. 7.
British Standards are the standards produced by BSI Group which is incorporated under a Royal Charter (and which is formally designated as the National Standards Body (NSB) for the UK).

An efficient condensing boiler will generate around 2 litres of condensate water an hour at a temperature of around 30-40°c. This needs to be safely disposed of, within the buildings waste water system. Industry specification and current British Standard 6798 states that ' wherever possible, the condensate drainage pipe shall be terminated

A photograph showing water tube boilers in build at the Colchester Works appeared in the July/September 1956 issue of British Machine Tool Engineering. The Company built a reasonable number of K-Types but very few VLs. Water tube boilers are particularly suitable for high pressure applications such as driving steam turbines.

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7-2,000 kPa or 1-290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
