Abstract:
1. A method for reducing energy costs during set periods in an ecological coal transformation process, comprising the steps of: a) storing combustible by-products generated during transformation of raw coal into ecological coal, and b) using said combustible by-products as an additional source of energy during said set periods, wherein step b) comprises the steps of: monitoring the energy demand, withdrawing at least part of said combustible by-products from a storage unit when the energy demand reaches a predetermined value, and converting the withdrawn combustible by-products into energy, wherein the step of converting the withdrawn combustible by-products is effected by burning the withdrawn combustible by-products so as to generate hot gases, and circulating said hot gases through a turbine to extract energy therefrom, and wherein said combustible by-products are stored under pressure into said storage unit.
