Bed-layer probing for solving air deviation problem in a molecular sieve adsorber;

In order to study the effects of the random movement and hitting of particles on the heat transfer in a gas-solid fluidized bed of big particles,th e heat transfer characteristics between the heating surface and the bed layer in a pulsed fluidized bed are studied experimentally.

81-9 type CFB boiler have been analysed by using SPSS software,obtaining the relational expression of oil-gun output,air flow rate,and bed pressure affecting the temperature rise rate of bed layer,as well as the relational expresion between the particle size of bed materials and the starting-up time.

Development and preparation of reactor bed fouling inhibitor for hydrotreating unit

Causes of pressure drop increasing too fast in hydrocracker beds with sour feedstock being processed, more severe equipment corrosion and impurity content increase in product were analyzed.

At a specific layer of a jig bed, its parameters as bulk density, true density, ash content, and density fractions bear a certain relationship.

The paper put forward a detection method of porosity of jig bed through analyzing slicing process of jig bed and introduced design of fuzzy control system of jigger s air valve and its implementation method based on the detection method.

Deviation between cost and government mandated price in bed utilization in public hospitals and corresponding strategy

Objective To identify the orthopedic disease needing rehabilitation nursing bed and formulate admission and transfer criteria for different disease.
