Abstract
All rotary Ljungstrom type pre-heaters have the problem is to optimize the number of rotation of the heat wheel. Due to the many sources of boiler inefficiency, the temperature of flue gas changes, it is necessary to change the number of rotation of heat wheel. This paper presents a logical scheme of operating the rotary Ljungstrom type pre-heaters, taken into consideration only the exit temperature of flue-gas changing the flow of natural gas, but also the number of rotation of the heat wheel.
