In article the solution of one of the problems facing developers of a heat power complex for highly effective use secondary and renewables reveals. The solved problem is a development of the circuit decisions providing tests of all set of the modes of cascade heatpump installation of a heat power complex, design of the test bench. The developed complex allows to use most effectively together with heatpump installations and thermal accumulators renewables. Also the complex uses also household overflows of energy for the consumer’s heat supply, as much as possible reducing consumption of organic fuel.

The results of a research of the water and chemical mode of boiler utilizers including determination of quality of saturated steam, nutritious and boiler water are given in article. Researches were conducted at the actual loadings and pressure and the average level of boiler water in a drum. The dependence of change of controlled indicators of quality of boiler water and saturated steam of a boiler utilizer on fluctuations of a purge size a copper and the set range of change level is established, and also dynamics of salinity of saturated steam depending on salinity of nutritious and boiler waters. We developed recommendations about control of additional indicators when carrying out chemical control at threat of various violations of the water and chemical mode. We gave an assessment of extent change a quality of boiler water when using on water treatment installations of membrane methods of desalting of initial waters. Also studied water and chemical modes can be used in units for recycling.

The paper has to shed light into understanding the waste useful and it has an aim to review about possibilities how to using different types of waste to generate energy. The paper highlighted the terms, that renewables it isn’t energy of the future but waste is – at least the future for the next hundred years. It’s very important to use waste by the right way, because of some current methods waste using have a low efficiency. There are several ways of using waste with pretreatment. Nowadays pretreatment includes torrefaction, pelletization, torrefaction of pellets (TOP) and wide spread around the world. It is necessary to compare economic indicators when you want to using some scenario. Using of waste can help us to reduce the pollutions and decrease load to an ambient. There are some advantages to using organic waste to generate energy – it can be considered as a fuel. But it also consists some negatives aspects such as low efficiency due to low thermal values (i.e. specific thermal capacity). Hence, waste using not so unequivocally as it seems at first sight. Thus, here is our understanding for this problem.

There are questions of increase in fusibility of slag in coppers with liquid removal of slag by additives on the basis of alkaline-earth metals are considered in the article. The optimum modes of additives dispensing by their giving in a zone of burning and a supply line of crude coal are under production conditions defined. Optimum doses of additives when burning the Donetsk anthracite are revealed. Methods of IR spectrums and the X-ray phase analysis investigated changes in structure of the studied slag samples at various modes of additives dispensing. The described methods can be also applied to units for recycling.
