Condensing Boilers Reduce Heating Energy Consumption

Condensing boilers reclaim that latent heat by condensing the water vapor and transferring its heat back into the return water, which increases boiler efficiency from 80% for traditional boilers to between 88% and 98%.

ENERGY EFFICIENCY BENCHMARKING STUDY OF FOOD MANUFACTURING

Majority of the boilers were steam boilers, which operated at pressures ranging from 7 to 16 bar. Most boilers (63%) use natural gas as the fuel, while diesel (25%) and town gas (12%) were used by the remaining boilers. The operating thermal efficiency of steam boilers varied from 75 to 83%.

Hartford Steam Boiler paid $600,000 as part of steam turbine claim because the inspections and investigative work after a failure did not find all of the broken parts. In this particular incident, the last blade stage of the low-pressure turbine encountered a water induction incident as a result of a high condenser hotwell level.

their insulating effect may still result in reduced boiler operation efficiency and energy wastage by allowing excessive heat to exit the boiler with the stack gas. As discussed earlier, deposits may also lead to differential corrosion cells beneath their surfaces. The result is localized corrosion or pitting.

(69) Unfired Steam Boiler--An unfired pressure vessel in which steam is generated. The term does not include: vessels known as evaporators or heat exchangers; or vessels in which steam is generated by using the heat that results from the operation of a processing system that contains a number of pressure vessels, as used in the manufacture of chemical and petroleum products.

The deaerator system should be designed to maintain a constant operating pressure and temperature within the deaerator through all operating ranges. Several design suggestions should be considered. First, install a pressure-reducing valve in the steam line that feeds the deaerator, with its sensing line inside the deaerator itself.
