“…For sulfate-bound deposits the coefficient of thermal conductivity is slightly less than 0.1 W/mK, for ferriferous it lies in the range of 1.4 to 1.5 W/mK. The contact resistance according to the experimental data [6] is a function in terms of temperature: r k = -7.247 10 -7 T + 0.000647…”

Abstract.One of the problems of thermal power plants is the contamination of heating surfaces that arises during the boiler unit operation while combusting the solid fuel. The main part of the energy is consumed by pipes forming the furnace. Non-combustible mineral part of the fuel in the form of the ash and slag accumulates on the heating surfaces and thereby prevents heating of the working liquid. Therefore, boiler requires higher fuel consumption to maintain the operating conditions. Violation of the thermal conditions of heating surfaces in consequence of contamination causes the negative effects on metal pipes right up to failure. This problem is urgent due to the fact that information about the process of slagging and its effect on the thermal conditions of the heating surface operation enables the possibility to minimize the negative consequences. This possibility is achieved by adjusting the thermal conditions of the combustion process in the furnace with the periodic cleaning of the heating surfaces.

Abstract. The relevance of the work is caused by reorientation of the modern power engineering to use of local low grade fuel resources. Some types of low grade fuels (peat, brown coal, sapropel, wood chips) are considered in this work. Thermotechnical characteristics of the investigated fuels and products of their thermal recycling are determined. Thermal recycling process is accompanied by release of fuel dissociation heat (0.33-3.69 MJ/kg). The results of thermal low grade fuel recycling are solid carbonaceous product (semi-coke) with a calorific value higher in 1.5-7 times than the value of natural fuels; pyrolysis resin with calorific value 29.4-36.8 MJ/kg; combustible gas with calorific value 15.16-19.06 MJ/m3.

Abstract. In this article are described the prospects of peat and wood using as a raw material for gasification with producing of high potential synthesis gas. It is shown that the low-grade fuel recycling, in particular wood and peat makes a use of this energy sources a possible alternative to the using a more traditional coal and natural gas. The features of low-temperature pyrolysis are analyzed and computer modeling of this process at different conditions is conducted. The temperature influence of recycling to main parameters (calorific value, elementary composition of gaseous components) of produced gas is established.
