New technologies must be implemented in order to use compressed gas energy on oil and gas fields rationally. The lack of cheap and reliable equipment leads to poor progress in this area. That is why development of the reliable and easy-to-use turbines for conversion of the gas stream energy to other types of energy is very important nowadays. Additionally, due to well-known problems of the climate change researches have to search for the new ways of additional energy generation without utilization of hydrocarbons. Compressed gas energy might be converted to heat or electrical energy and such options of the technological chain are the most demanded for the arctic regions.
The experimental sample of the heat energy generator is being developed within the scope of the ongoing research studies. One of the most important elements of the generator is turbine which converts compressed gas energy into mechanical energy. Then mechanical energy is converted to hydraulic energy in the pump which pumps the heat agent. The pump is attached to the turbine via transmission. Different types of the transmission might be used, including mechanical and electromechanical.
Maximum rotor mass reduction was the objective of the new turbine development process. Small rotor mass leads to better balance and some additional opportunities for the rotor rotation speed increase with wider area of application of such a turbine. Possibilities of turbine usage without a stator were considered during the designing stage and turbines from the active turbine group are of the particular interest in this case. Turbine blades must be thin, but strong at the same time and that is why loop type blades are considered. It is well-known fact that majority of the design studies are based on the experience accumulated by a huge number of specialists and this principle is important to use, including the information from patents databases.
In order to test the working efficiency of the considered machine – elements and joints models are created. Conversion of the compressed gas energy to mechanical energy principles was tested. Principles of the conversion of mechanical energy to electrical energy and further to heat energy were tested using electromechanical transmission.References
