Modeling and Control of Burning Process for Industrial Boiler

LIU Jun-yao

2001, 27(3): 1-3.

<Abstract>(74)

Abstract:
Process outputs are usually affected by the unmeasurable disturbances, so that it is difficult to get a satisfied performance in the burning process. An inferential technique is adopted to solve the problem in this paper. The effect caused by those factors can be estimated from the measurable output, then the disturbances can be reduced and overcame by using an inferential controller.

An Experimental Research of Anti-poison Catalytic Sensor

WANG Ru-lin, ZHANG Zhi-gang

2001, 27(3): 4-6.

<Abstract>(23)

Abstract:
The catalytic methane sensor will be poised when it works in the atmosphere with the sulphuretted hydrogen, which makes a serious effect on the stability of the working sensor. The paper analyzes the innate character of poising devitalization of the sensor and gives the common tactic of platinum palladium catalyst system of anti poison by experimental research.
