The heating surface is the most important technical parameter of a mine calorifier plant. Analysis of the heating surface area of this surface is made on a large body of project data of mine calorifier plants of various Giproshakht institutes (Mosbaosgiproshaht, Lengiproshaht, Donetskgiproshaht, Uralgiproshaht, etc.). As a specific criterion of comparison, taking into account the numerous factors influencing the size of the required heating surface, it is advisable to consider the technical indicator of mine calorifier plants. Let's call it specific heating surface, i.e. the number of square meters of the heating surface of the mine calorifier plant, per 1000 kcal of heat transferred to the air per hour.

In the design and operation of mine heater installations, the amount of electricity consumed and the installed power of the fan drive are of great importance. Let us analyze these data using the example of several Giproshakht institutes.
