Tool for own communal services enterprise, city budget, and investors resources efficiency improvement for energy conservation measures implementation at heat, water and wastewater enterprises is considered. It is shown that key role in the efficiency improvement plays performance contracts between enterprises and city's authority.

Keywords: energy conservation measures, communal services enterprise, economic incentives, implementation tool.

Prospects of the use of population waste products (rubbish & sewage) as a nontraditional energy source are considered Their industrial utilization at the 7 largest cities of Ukraine will make it possible to produce 10-13 TWh of electrical energy and to reduce consumption of organic fuel by 3 5-4 6 mt of conventional fuel.

Keywords: population waste products, rubbish, sewage, industrial utilization, waste products burning, methane recuperation, production of electrical energy.

The levels of use of combustible secondary energy resources (CSER) and determined the direct costs of energy sources in their preparation for combustion in power plants. As of 2009, the total output of CSER was 9317.3 thousand the, from which the used 8059 (86.5 % of output), losses - 1258.3 (13.5). For certain types of CSER: losses are blast furnace gas - 450.5 thousand tons of standard fuel (7.58 % of total output), converter gas -397.7 (98.39), ferroalloy gas - 153.1 (66.42), waste from logging and wood processing – 28.5 (22.82), black liquor fully utilized.
Direct costs of energy resources for the preparation of the above species of CSER are minor and are as follows: for the blast furnace gas - 3.77 kg of standard fuel/tce (blast furnace gas is given to the value of fuel through its heat of combustion), converter gas – 1.2 and ferroalloy – 1.64. Given the structural changes in production sources of CSER, assess their potential for possible use in the near future, whose value may be in the range 1.0 - 1,1 million tce.
The article presents data on the costs of energy for hydrogen production using different technologies. These costs far exceed its energy potential. According to this analysis, the total costs of energy resources for 1 ton of hydrogen contained up to 1 ton of fuel equivalent are within 1.6-5.1 tce.


Keywords: secondary combustible energy, yield, utilization, loss, blast furnace, converter, ferroalloy gases, hydrogen.

An analysis is conducted and the estimation of possible power potential of separate alternative types of fuel is given, direct expenses of energy supply on their booty, production and preparation to incineration in steam generating units. The followings types of fuel are considered: peat, wastes of the timber cuttings, agricultural biomass, mine methane.
General power potential of the indicated types of fuel after a separate variant makes 9360 thousands of conditional fuel, including peat is a piece – 1700, wastes of wood – 1700, straw of corn cultures – 3800, mine methane – 1000.
Direct expenses of energy supply on a booty and preparation of alternative types of fuel resulted to 1 kg of conditional fuel, followings: peat is a piece are 23,9 kg of conditional fuel, peat milling – 49,7; peat briquettes – 143,5; straw in bales – 31,0; straw in briquettes – 170; straw in granules – 238,3; wood on condition of its gasification – 240,8; mine methane – 151,0. Got values of direct power expenses on preparation of alternative fuels to incineration except for peat of piece exceed analogical indexes for the traditional types of fuel.


Keywords: alternative types of fuel, power potential, power expenses, power efficiency.

In the article the indexes of complex estimation of innovations are offered in industrial technologies for making a decision in relation to expedience of their introduction. The example of calculation of efficiency of introduction of technology of the «dry extinguishing of coke» is resulted for substituting for technology of the «wet extinguishing».

Keywords: efficiency energy index, energy inputs and energy total inputs, total power intensity.
