Row is unstable (being directed to existing inferior raw material)；Mating air separation unit is needed, one-time investment is big, and industrialized unit is not yet universal；It is right
Coal is selectively strong；Carbon dioxide is high in coal gas, and methane content is high, available gas 65-72%；Single furnace gas production is high, about between
1 times of having a short break or more；It is always continuous upper blowing gas, no blowing-out gas is vented, and environmental pollution is small.
Fixed-bed intermittent gasification process is mostly used at present, fixed-bed intermittent gasification process process is simple, using air, steam
Gasifying agent oxygenation air gas stage by stage belongs to accumulation of heat gas making method, and temperature difference amplitude is big, and gas overall quality is good, especially blows down
In the stage, makings is more preferable than above blowing, and the current energy consumption of the technique remains high, and main cause is blowing heating using air, the thermal efficiency
Difference, heat loss are big.Oxygen-rich gasification is continuous upper blowing gas, the self-heating gas making method that heat supply and gas processed carry out together, temperature difference amplitude
Small, gas production is big, and environmental pollution is small, but carbon dioxide, methane content are high in coal gas, and the continuous and steady operation time is short, is gasifying
Easy slagging agglomeration, needs timing blowing out manually to take off block processing when inferior raw material.
