High Efficiency Furnace Venting: What You Need to Know

Mar 18, 2019 · A high efficiency condensing furnace can achieve efficiency ratings of 90 or above. It uses a venting system to extract that heat before venting. What is vented is a residual corrosive condensate of water and carbon dioxide. This residual liquid is highly acidic. It will ruin the standard venting equipment that is used in conventional gas

How to Run a Coal Fired Boiler at the Best Efficiency

Jul 05, 2009 · Boiler efficiency is mainly depended on the amount of losses in the system. In high capacity pulverized coal fired boilers the total losses account to about 12 to 14%. Roughly 50% of the losses are governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The other 50% losses are carbon loss and dry gas loss.

Boiler Efficiency - an overview | ScienceDirect Topics

The boiler efficiency of modern pulverized fuel, hard coal-fired units is 94%–95% (LHV basis), reducing slightly to 90%–91% for lignite-fired units due to the higher moisture content. When combined with the other elements of the Rankine cycle, the overall efficiency currently achievable in conventional plants is in the 40%–45% range.

Supercritical steam generator - Wikipedia

A supercritical steam generator is a type of boiler that operates at supercritical pressure, frequently used in the production of electric power.. In contrast to a subcritical boiler in which bubbles can form, a supercritical steam generator operates at pressures above the critical pressure – 22 megapascals (3,200 psi).Therefore, liquid water immediately becomes indistinguishable from steam.
