Method of preventing energy loss, self-heating and self-ignition in peat stacks

摘要

The invention relates to a method of preventing the energy loss, self- heating and self-ignition of a peat stack. The rick storage of peat is often connected with a heating caused by exothermal reactions, which causes energy losses of the peat and even self-ignition. This problem has been solved by conducting inert protective gas into the stack, by which the air present in the stack is displaced or diluted and thus the aerobic exothermal reactions of the peat are prevented. It is preferable to insert inert protective gas in a liquid state into a stack heated up to critical point or into the heat centre of it, the gas rapidly cooling the stack or the centre and thus preventing even more efficiently the ignition of a stack fire. Covering the stack with a cover like a plastic foil considerably prolongs the presence of the inert-gas in the stack and thus improves the effect of the inert-gas treatment.
