Transfer of kilns to pulverized coal fuel

I propose to consider the possibility of cooperation in transferring the operation of kilns from gas fuel, by substitution, to mechanically activated coal dust. Economic feasibility, as a criterion, is calculated individually in each case. On average, the reduction in the cost of thermal energy production is several times in favor of coal fuel. Available coal of the gas group is used as fuel. Thermal performance may vary. We are considering and discussing options for cooperation.
