WTA offers big efficiency gains - Modern Power Systems

Dec 01, 2007 · The radial air staging represents state-of-the-art for modern bituminous coal firing systems. In addition to the primary and secondary air supply, two overfire air levels can be employed. Thanks to the efficient air staging, compliance with the EU emission limit levels for NOx and CO is ensured, as has been demonstrated by CFD analysis, in turn verified at dry-lignite-fired test facilities.

Indirect firing | Industrial Efficiency Technology & Measures

Indirect firing Historically the most common firing system is known as the direct-fired system, where coal is dried, pulverized and classified in a continuous stream, and fed directly to the kiln. This can lead to high levels of primary air (up to 40 % of stoichiometric).

Firing Systems | ERK Energy Systems

Our first combustion system dates back to the 1950's and had a 2 megawatt water-cooled inclined grate for biomass firing. Thanks to our experience with in-house water circulation, the combustion system was integrated into the boiler's natural circulation to achieve optimal cooling of all components exposed to high temperatures.

IGCC System | Nakoso IGCC Power GK

IGCC is more efficient than conventional pulverized coal firing systems, and CO 2 emissions are reduced by about 15%. IGCC can also reduce the volume of coal ash and the amount of cooling water discharge. The volume of ash is reduced by around 50% since the ash is dissolved as glassy slag instead of coal .
