WIND ENERGY IN THE MANUFACTURE OF PENOSTEKL AND KERAMZIT

Objectives. Foamglass and expanded clay are absolutely fireproof, reliable and environmentally friendly heat insulators. But in the cost of their production, energy costs reach 40 ... 60%.

Method. A part of the thermal energy required for the production of building materials was proposed to be developed by a wind power station (WPP).

Result. A heating plant with a Darya turbine capable of operating in severe climatic conditions has been developed. The bearing part of the wind power installation consists of three simple masts, working mainly in compression. The masts are symmetrically placed relative to the center of the wind farm. The design feature is that the vertical shaft with the turbine is suspended at the top of the swivel at the point where the three almost horizontal cables meet. The free ends of the ropes pass through the blocks on the tops of the masts and are secured with anchors at ground level. Therefore, the shaft works mainly in tension and torsion and is well opposed to transverse vibrations. A simple generator without equipment for voltage and frequency regulation operates at WPPs, as for electric heaters of furnaces to which the generator current is supplied, power conditioning is not required. With a decrease in wind speed and a drop in HPP power, the automation supplies more fuel to the burners to maintain the temperature according to the regulations.

Conclusion. Thus, the WPP capacity fills a part of the required heat output of the furnaces, and the missing part of the heat output is compensated by burning gas or fuel oil. If the WPP is located near the enterprise, then electricity is supplied to the consumer without transformers. It is cheaper to lay cables of a larger section than to complete a wind farm with two power transformers.
