Pulverized coal-fired boiler - Wikipedia

Temperature inside boiler (furnace) is around 1100 deg to 1200 deg. Although it is favorable to keep it under 1100 deg or otherwise ash in flue gas will melt as forming clinkers and it will stick to to boiler walls. I am talking about big boilers of 800MW (super critical) capacity. Output main steam temperature ranges from 550 to 570 deg.
