An innovation created by a Bulgarian scientist is said to be able to make natural gas use more efficient and cut down the expenses for central heating.
The invention, which is a steam and gas turbine installation, can produce the same amount of heating and electric energy with about 30 percent less natural gas. The installation costs BGN 56 M, but its efficiency may save a big heating utility, like the one in the capital Sofia, up to BGN 500 M in the long run, Prof. Nikolay Kolev, the inventor of the facility, has stated.
The energy saving invention was presented Thursday on the Bulgarian Academy of Sciences' presentation of its latests designs.
