Nov 19, 2006 · Steam or water does not need to be the condensing agent. My Dunkirk Quantum uses the cold intake air as a condensing meduim to cool the exhaust to much lower temperature. The exhaust on the boilers runs about 20F BELOW the water temperature and the boiler continues to condense up to 180F water temperatures, or so.

So, for a boiler that produces 210 kW (or 700,000 BTU/h) output for each 300 kW (or 1,000,000 BTU/h) heat-equivalent input, its thermal efficiency is 210/300 = 0.70, or 70%. This means that 30% of the energy is lost to the environment. An electric resistance heater has a thermal efficiency close to .

The present invention provides a process for the control of a cleaning system for a boiler which incorporates factors related to the overall operation and efficiency of the boiler. Current values of plant data parameters associated with the boiler furnace are compared with respective setpoint values. The process then determines if the furnace is to be cleaned based on this comparison.

Nov 21, 2016 · With thermal fluid heaters, the efficiency is known to be higher than with conventional steam systems.Flash losses in a typical steam system can be 6% to 14%. Add to that blowdown losses up to 3% and de-aerator losses of 2%. Clearly, the difference in the efficiency of the two systems is pronounced as thermal fluid systems do not suffer any of these losses and can operate up to 30% …

Boiler Operations That Affect Efficiency. In its simplest form, efficiency is the ratio of energy output to energy input, expressed as a percentage. To optimize efficiency, therefore, it is important to minimize input (fuel being a major source) and maximize output (steam production). However, these two goals often have opposing outcomes.
