Abstract

The results of a complex fuel additive tests - the intensifier of the combustion process on a coal boiler KV-r-11.63-115 - are presented. An increase in the efficiency of the boiler unit by 5.1% (abs) was recorded with a corresponding reduction in the consumption of conventional fuel for the generation of a unit of thermal energy.Application of the intensifier allowed to solve the problem of cleaning the waterfall tubes from the layer of annular deposits and to change the structure of the slag formed during the combustion of coal, which became more homogeneous and without the center of agglomeration.

Highlights

Nowadays, more than a quarter of the world's demand for various types of energy is met by burning fossil fuels

Summary

Introduction

More than a quarter of the world's demand for various types of energy is met by burning fossil fuels. Further increase in the energy produced by burning coal and, the development of energy, is impossible without the development and implementation of effective ways to reduce the negative impact on nature. One such method is the combustion of coal fuel with added additives. As a result of the additive action, the conditions and the mechanism of the course of all physical and chemical, including oxidation-reduction reactions, change the temperature gradient throughout the combustion volume, reduce the need for atmospheric air necessary for burning fuel, reduce the number of products of incomplete combustion and several the quantity of products of complete combustion increases.
