1. This paper fulfils the automatic-mix-control of high caloricity gas and low caloricity gas using the intelligent control and the single neuron adaptive PSD controller.

2. The composite control system with"prefeed"and "backfeed"which controls caloricity more sensitive, accurate and faster than the one just with"backfeed"is involved.

3. Natural gas caloricity gaging is more scientific and impartial than volume gaging and mass gaging.

4. The invention relates to a new waste burning hot gas flow generate device which can solve the problems of the waste of our country with much water, lower heat quantity and large caloricity change.

5. Perillartine is a fine sweetener and antiseptic that possess high sweetness, low caloricity and safety. It is widely applied in cakes, beverage, tobacco, toothpaste, medicine, etc.

6. In order to reduce the erosion of water-wall, large furnace sectional area should be selected by boiler works, and the power plant should select the coal caloricity close to the designed for use.
