WASTE INCINERATION GENERATOR PLANT AND LOAD CONTROL METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To improve follow-up performance to varying power demands, by adding a precedent operation means to a combustion air quantity adjusting means and a waste charge rate adjusting means, and adding a waste charge rate delay operation means at a load variation first stage and the waste charge rate accelerating operation means at load variation second stage. SOLUTION: A precedent operation means is added to a combustion air quantity adjusting means 52 and waste charge rate adjusting means 51, and adding a waste charge rate delay operation means at a load variation first stage and the waste charge rate accelerating operation means 51 at load variation second stage. In the combustion air quantity adjusting means and waste charge rate adjusting means 52, for the precedent control of the combustion air quantity according to the change ratio of a load demand value, a target value of the combustion air quantity is computed, based on specified equations. A charge rate accelerating operation function in the waste charge rate adjusting means 51 recovers the delay of the charge rate at the load variation at first stage, and at the load variation second stage the waste is charged in precedence of the load demand value to avoid the response delay.
