GE pulverized coal boiler is generating steam for today’s large scale global power projects up to 1350 MW electrical for coal units at pressure and temperatures that can reach the service limits of contemporary materials.

Increased efficiencies

High cycle efficiencies at ultra-supercritical conditions, reaching 44 to 47% on an LHV basis (42 to 45%), leading to cleaner operation and lowered fuel consumption.

Lowered emissions

Low primary NOx emissions using advanced tangential firing systems and effective overfire air arrangements, resulting in less reagent consumption and SCR catalyst material.

Enhanced Flexibility

Two-pass boilers have outstanding operational flexibility for temperature control, grid code requirements, sliding pressure capability, and load cycling. The boilers also feature reduced construction time and cost using advanced construction techniques and standard component design and fabrication.

Two-Pass Boiler

Radiant pendant surfaces are located above the furnace, and convective surfaces are arranged horizontally in the second pass. The two-pass heat exchanger configuration results in an efficient furnace height and a lower cost of construction. Our patented tilting tangential firing system accommodates the large spectrum of fuels found across the globe (multiple grades of coal, oil, gas, heavy residues, biomass and other opportunity fuels), and is a leader in primary emissions control.
