Help: Coal consumption of a 4 million BTU heat transfer oil furnace
Thread Content
This post was last edited by zgj2405 on 2011-1-9 08:32. Question: What is the coal consumption per hour for a heat transfer oil furnace with a capacity of 4 million kcal? What is the amount of ash? What types of coal feeding equipment, ash removal equipment, and dust collectors are suitable?
The question wasn’t clearly stated; it’s necessary to specify what type of furnace and what kind of coal is used
400kcal/h = 400*10000*4.18 kj/h = 1672*10000 kj/h = 16.72*1000 mj/h = 400*10000*4.18/3600 kW = 4.64 MW; calculated in this way, it’s equivalent to a small furnace with a capacity of over 6 tons. Ordinary coal has an energy content of 15–22 MJ/kg; approximately 1 ton to 1.5 tons of coal is consumed per hour. It’s around 5 tons. Assuming the worst-case scenario for ash content, 30% means an ash output of approximately 300–450 kg/h. For coal feeding equipment, a bucket-type conveyor driven by a motor will suffice. For slag removal, if there is an ash tank, circulating water can be used; otherwise, manual handling is required. For dust removal, water spraying is sufficient

Our company specializes in the recovery of waste heat from the flue gas of heat transfer oil boilers; we convert the thermal energy contained in the exhaust gases from these boilers into steam for use in production. If you are interested, please call us
It depends on what type of coal you’re burning, as well as your thermal efficiency; it’s sufficient to know all of these things
I also want to learn *how to do the calculations. I don’t know which book covers this topic? Give some guidance; I’ll learn it on my own*
4 million BTU heat transfer oil furnace: What is the coal consumption per hour for a 6-ton furnace? :What is the amount of slag for 1.2 tons (based on 4800 kcal)? :2. For hoists, what type of coal feeding equipment is suitable? Lift buckets. For ash removal equipment: scraper slag extractors. For dust removal: multi-tube dust collection towers
