Conference Article: Testing of high temperature components in the component testing facility (KVK)

Jansing, W. (INTERATOM GmbH, Bergisch-Gladbach (Germany))

Abstract

The Component Testing Facility (KVK) is used for the experimental testing of high temperature components for nuclear coal gasification. It went into operation in August 82 after a planning and construction period of two and a half years. Design and mode of operation are described. The thermal power is 10 MW (maximum 12,8 MW). The temperature in the primary system amounts to 950 deg. C (maximum 1000 deg. C). The system pressure is 40 bar (maximum 46 bar). The nominal flow is 3 kg/s (maximum 4,3 kg/s). The helium velocity in the hot-gas duct is 60 m/s. The maximum achievable temperature transients are +- 200 K/min. The maximum achievable pressure transient is 5 bar/s. This report covers the operating experience and test results as well.
