[0034] In the present invention, the preparation method of the anthracite composite fuel preferably comprises the following steps:
[0035] Anthracite powder, gas coal powder, plant fiber, binder, desulfurizer and water are mixed to obtain anthracite composite fuel.
[0036] In the present invention, the amount, source and type of the anthracite powder, gas coal powder, vegetable fiber, binder, desulfurizer and water are the same as the anthracite powder, gas coal powder, vegetable fiber, binder described in the above technical scheme. The dosage, source and type of , desulfurizer and water are the same, and will not be repeated here.
[0037] The present invention has no special limitation on the mixing method of the anthracite composite fuel, and the mixing technical solution well known to those skilled in the art can be adopted.
[0038] The present invention provides a composite briquette, which is made from the anthracite composite fuel described in the above technical s...
