Steam Boiler - Steam Generator

Localised rapid steam generators provide a useful way of generating small amounts of steam for local process heating. They are compact, lightweight units that produce high-pressure steam very quickly from a cold start up and can be used to eliminate old inefficient centralised steam boilers and distribution systems.

To be eligible for Enhanced Capital Allowances localised rapid steam generators must have a thermal efficiency of at least 88% (based on net calorific values). Additionally localised rapid steam generators over 400kW must incorporate burners and controls that offer equivalent standards of performance.

Thermal efficiency must be determined under the following standard test conditions in accordance with BS845: Part 1:1987 or similarly agreed procedures within European Standards (or pre-standards). Where BS845: Part 1: 1987 is used, the standard test conditions are: a maximum ambient air temperature of 25 degrees Centigrade and an excess combustion air level of 15%. The boiler must be operating at its maximum continuous rating (i.e. 100% MCR) during the tests.
