[0029] Example: A coal gasification synthetic ammonia urea project
[0030] A project with a daily output of 1,000 tons of synthetic ammonia intermediate products and 1,740 tons of urea requires coal gasification to produce 88,000 standard cubic meters of effective syngas (CO+H2) per hour.
[0031] The raw coal is a domestic commodity coal, with a moisture content of 14% on a received basis and an ash content of 7% on a dry basis. According to elemental analysis on an anhydrous and ash-free basis, it contains 80.72% carbon, 4.83% hydrogen, 1.03% nitrogen, and 0.45% sulfur. The base low calorific value is 25MJ / kg.
[0032] Set up a multi-burner cold-wall pulverized coal gasifier with a daily coal input capacity of 1,350 tons.
[0033] An average of 56 tons of raw coal is consumed per hour. The medium-pressure roller mill is used in the coal grinding unit to grind into pulverized coal, which is stored in a low-pressure coal bunker.
[0034] The pulverized coal enters the high-...
