STEP 3 SELECT THE BOILER The size of the replacement boiler will be based on the Total Heat Loss of the building calculated in Step 2. The boiler should be selected based on its Net I-B-R Rating in BTU/Hr. For example, if the Total Heat Loss of the house is 85,000 BTU/Hr. then the Net I-B-R Rating of the replacement boiler must be at least 85,000.

Aug 16, 2017· However the heat lost from the boiler jacket, piping losses and pick-up allowances are assumed to contribute to the building’s heating load. This assumption means the boiler and piping is thought to be located in the heated space. The Heating Capacity rating will always be higher than the IBR Gross output rating because of this factor.

Steam turbine - Wikiped

A steam turbine is a device that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884.. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in ...
