It is proposed to perform complex reconstruction of the heating system for high heating ladle stand, including design, coordination of the working draft, completing the necessary equipment, installation supervision, commissioning and commission, followed by warranty.It is proposed to construct heating system using regenerative burners, usage of which reduces the consumption of natural gas in 2 times. Regenerative system with deep heat utilization of combustion products has the following advantages: 1. Regenerative system provides air heating going to burn up to 0.85 on the temperature of combustion products in setting (temperature of combustion products is about 1250 °C, the temperature of air heating is about 1060 °C). 2. Deep heat utilization of the combustion products can save on natural gas from 50% and higher. 3. Regenerative burner system is working in pulsed mode (on / off). The temperature in the ladle depends on the burners working time. This approach allows to work at a constant ratio of gas-air, that is more economical in comparison with proportional control. 4. The temperature of outgoing gases is up to 150 ° C, what will facilitate their removal and reduce the thermal pollution of the environment. 5. Reduction of natural gas consumption in 2 times would lead to smaller volume of air combustion for stands operation in 2 times and electricity costs will decrease in two. 6. The volume of outgoing gases, which are taken by exhauster, will be reduced by reducing the amount of supplied gas and air. Exhauster capacity and therefore energy costs are reduced by 50%. Burners operate alternately, first burner at first, and then the second one, with the cycle of 60-90 seconds. To change the direction of air flow and smoke the mechanism of transferring is installed. Air pressure for pneumatic cylinders provided by the energy-equipment shop, and for the filing of the contingency air air compressor is installed.
