What is the relationship between the power generation capacity in MW of a power plant and the amount of flue gas? !
Thread Content
When discussing flue gas desulfurization in power plants, the power generation capacity of the plant, expressed in xx MW, is used to indicate the size of the plant’s boilers. What I want to ask is: there should be some approximate correspondence between this xxMW value and the size of the boiler as well as the volume of flue gas. What size of boiler or what volume of flue gas corresponds to this MW value? ! Thank you! !
I posted in the wrong thread; the original poster should post this in the environmental protection section. The relationship between MW, boiler output, and flue gas volume (in large coal-fired power plants): 300MW → ~1000 tons per hour (boiler output) → flue gas volume of 1–1.2 million m3/h (you can remember this as 1 million cubic meters). For 600MW and 1000MW, the calculations are simple: 600MW → ~2000 tons per hour (boiler output) → flue gas volume of 2–2.3 million m3/h (remember this as 2 million cubic meters); 1000MW → ~3000 tons per hour (boiler output) → flue gas volume of 3–3.6 million m3/h (remember this as 3 million cubic meters). When expressed in terms of boiler output, the flue gas volume generated per ton of steam in large power plants is approximately 1000 m3 per ton of steam, which is an integer. In the case of smaller boilers, the flue gas volume per ton of steam is much higher than 1000 cubic meters, usually ranging from 1200 to 1500 cubic meters. The larger the boiler, the higher its efficiency, and thus the less flue gas it generates – similar to how larger chemical plants have lower energy consumption. So once you remember that for 300MW, it’s 1000 tons and 1 million cubic meters, it will be easy. .
