EXPERIENCE IN OPERATING OF 1,16 MW STEEL HORIZONTAL HOT-WATER BOILER (KSGN-1,16)
For the CIS countries and Kazakhstan, there is currently an increase in decentralized heat supply systems equipped with small hot water boilers with a capacity of up to 7,56 MW. For the Almaty city there is a large number of small gas-fired boiler plants operating hot water boilers with a capacity of 0,63 to 7,56 MW for which the requirements of efficiency and environmental attractiveness must be met when operating existing units, replacing and upgrading them, and when commissioning new boilers. The article describes the design features of the KSGn-1,16 series boiler units and shows the experience of their operation with an assessment of their efficiency. A new design of new U-shaped furnace screens formed from all-welded membrane tube panels was noted. Internal and external U-shaped screens are used, and the last is acting as a bi-radiated screen. Monitoring the operation of boiler plants with the KSGn-1,16 series boilers and conducted heat engineering tests allowed to obtain confirmed information showing that the boilers of this series have high reliability, maintainability and operational efficiency. The processed results of research on the operation of boilers are presented. it is shown that the boiler has high specific characteristics of thermal efficiency.
