Arrangement for the combustion of high-viscosity heating oils in multi-stage pressure-atomising burner plants

摘要

The invention relates to an arrangement which makes it possible to burn high-viscosity heating oils with a pour-point greater than the ambient temperature in pressure-atomising burner plants with multi-stage operation. The aim of the invention is to combine together tuyeres which are known per se to result in sufficient preheating of the components through which the heating oil reaches the nozzle. The object is achieved in that the additional tuyeres and the tuyere with a pressure-adjustable valve have preheated heating oil flowing through them successively or simultaneously in either parallel or series arrangement in a preheating circuit, the inlet connection and outlet bores or overflow bores being arranged in such a way that an optimum heat transfer is achieved.
