ABSTRACT:
A plant for the incineration of waste, primarily from retreading shops, with the simultaneous use of the energy content of said waste for steam regeneration to operation and heating. The rubber waste is dosed in an amount dependent on the heat need of the shop with a screw to a grinder where it is ground down into small particles which, mixed with air, are blown into a furnace mounted onto the bottom of a steam boiler. By means of the blowing into the furnace as well as the blowing of flue gas at high temperature in the boiler taking place tangentially, a long period of stay for the burning particles is obtained, thus obtaining a total incineration. The outgoing flue gas is purified prior to release in the usual manner. The furnace is provided with an oil burner, which, in the event of a low energy need in the plant, has sole responsibility for steam regeneration over the oil system and control equipment. The plant is also suitable for less incombustible fuels and waste in powder or liquid form, for example, plastic waste, coal dust or biomass, the latter even mixed with water or oil, as well as solvents, tars, etc.
