Introduction

For the last 30 years personnel of Boiler Plants and Ecology in Power Engineering Department of the Moscow Power Engineering Institute – MPEI (TU) in collaboration with the staff from thermal power plants and design organizations have been widely implementing the methods of staged combustion of gas, oil and coal. For that purpose more than 100 power and water-heating boilers of different types were reconstructed. The main goal of this activity was to improve dependability and efficiency of boilers as well as to reduce nitrogen oxide emissions into atmosphere.
