ASPECTS REGARDING THE CONCEPTION, DESIGN AND CONSTRUCTION OF RECUPERATIVE BURNERS

Abstract

This article presents the main aspects of the conception, design and construction of selfdesigned recuperative burners. The starting point of the article is the operating principle of this specific type of combustion plant. This operating principle is based on the preheating of the combustor (combustion air) by taking over an important part of the enthalpy of its own combustion gases. Based on this principle, the recuperative burner of our own design has an energy efficiency that consists in reducing the specific consumption of fuel (natural gas) by about 25-35%. Also, the use of this specific type of combustion plant provides other functional advantages such as: a higher temperature in the hearth (due to a complete combustion), reduction of technological cycle times for the realization of various processes. The article also presents some functional parameters of a type-dimensional range of recuperative burners of our own design.
