 By decree of the Presidium of the Supreme Soviet of the Ukrainian SSR dated May 3, 1954 Nikolay Dobrokhotov was awarded the Order of Lenin and by decree dated July 19, 1958 he was awarded the Order of the Red Banner of Labour.

Scientific and applied activities
In 1921 was published the first scientific paper of Nikolay Dobrokhotov "About burning of oil shale in the gas generators". Nikolay Dobrokhotov created a new theory of furnaces, which was fundamentally different from the hydraulic (prevalent in the 1930s) in the substantive provisions and practical conclusions. He first showed that the movement of gases in furnaces is turbulent and not laminar in nature, and therefore the processes of mixing gas and combustion of fuel run through the laws of the turbulent and not laminar flow. Its essence is as follows:

to improve heat transfer by convection and radiation, gases must move in the working space of the furnace as close to the surface of the heated subjects with the greatest possible speed;

combustion of fuel at high temperatures is determined by the conditions of mixing it with oxygen. The chemical reaction of combustion occurs very quickly and does not limit the rate of fuel combustion process;

length of the turbulent flame is proportional to the diameter of the fuel jet and does not increase with increasing of heat load at a constant ratio of fuel and air;

geometric pressure of gases in furnaces is small in comparison with the kinetic energy of gases. Effect of geometric pressure can be neglected, considering only the forces of inertia and kinetic energy of gas flows.

capacity of the furnace is necessary to determine not only by the quantity of supplied fuel in it, but the oxygen consumed by the furnace for combustion of fuel;

the choice of transporting system of processed and received materials in the furnace, which determines the type of the furnace and is its main feature, is very important.

This theory has opened new directions in the design of compact furnaces with forced movement of gases.

 Scientific and applied action 
 In 1921 was published the first scientific newspaper of Nikolay Dobrokhotov " About combustion of oil shale in the gas generators ". Nikolay Dobrokhotov created a modern theory of furnaces, which was basically different from the hydraulic (prevalent in the 1930s) in the substantive provisions and practical conclusions. He first read that the movement of gases in furnaces is churning and not laminar in nature, and therefore the processes of mixing gas and burning of fuel run through the law of the turbulent and not laminar flow. Its essence is as follow: 

 to improve heat transfer by convection and radiation, gases must act in the work space of the furnace as close to the surface of the heated subjects with the greatest possible speed; 

 burning of fuel at eminent temperatures is determine by the condition of mixing it with oxygen. The chemical reaction of combustion occur very quickly and does not limit the rate of fuel combustion procedure; 

 length of the turbulent flame is proportional to the diameter of the fuel jet and does not increase with increasing of heat burden at a constant ratio of fuel and air; 

 geometric pressure of gas in furnace is belittled in comparison with the kinetic energy of gases. Effect of geometric atmospheric pressure can be neglected, considering only the force of inactiveness and kinetic energy of gas flows. 

 capacity of the furnace is necessary to decide not only by the quantity of supply fuel in it, but the oxygen consumed by the furnace for burning of fuel; 

 the choice of transporting system of processed and receive materials in the furnace, which determines the type of the furnace and is its main feature, is very significant.
