ABSTRACT: The paper presents a case study on the energy balance of coal mills for energy groups operating with inferior coal. It is analyzed the steam boiler energy group of 330 MW lignite-fuelled. Burning lignite takes sprayed form, in burners with slits. KEY WORDS : fake air, grinding fineness, lignite elemental analysis, lower power calorific value. 1. INTRODUCTION

The population problem isn't just a matter of the number of people. People consume food, fresh water, wood, minerals, and energy as we go about our daily lives. And producing food, pumping groundwater, harvesting wood, mining minerals, and burning fuel all deplete our resource base and produce pollution.

The basic function of the power plant is to convert energy in coal to electricity. Therefore, the first thing we should know is how much energy there is in coal. Energy content of coal is given in terms of KiloJoules (kJ) per Kilogram (kg) of coal as the Gross calorific value (GCV) or the Higher Heating value (HHV) of coal.
