Title: Method and apparatus for measuring respiration, oxidation and similar interactions between a sample and a selected component of a fluid medium
IPC: G01N27/76
Filed: 1989-12-01
Abstract: Atmospheric air is introduced into reference (20) and 
sample (21) chambers, whereupon alternating circulation of the 
gases in the two chambers through a carbon dioxide sensor (15), 
an oxygen sensor (16), a pressure indicator (17) and a pressure 
regulator (18) occurs before the gases are returned to their 
respective chambers (20, 21). The calculation of rate of 
production or consumption of carbon dioxide and oxygen by a

by a microprocessor (27, 28) which receives signals from the 
carbon dioxide (15) sensor oxygen (15) sensor and pressure 
indicator (17) and controls the circulation of the gases. 
Sensor drift is compensated for in the calculations through the 
use of multiple reference chamber readings and through volume 
determinations for the reference and sample chambers and the 
sensors.

Title: Apparatus for gasifying or combusting solid carbonaceous material
IPC: C10J3/56
Filed: 1990-02-22
Abstract: An apparatus for gasifying solid carbonaceous material in a circulating fluidized bed reactor (1). Particles are separated from the product gas at least in two stages so that in the first stage (2), mainly coarser, so-called circulating particles are separated and returned to the reactor. In the second stage (5), fine carbonaceous and ash-containing particulates are separated from the gas and are made to agglomerate at a raised temperature. Coarser particles thus received are returned to the reactor through a return duct (3, 33) together with circulating particles. Agglomeration is effected in a chamber (30), where a fluidized bed (31) composed of coarse particles is maintained. Fine particulate material (38) and oxygen containing gas (39) are introduced into the free upper part of the chamber so as to form a flame (40). The point of the flame penetrates into the fluidized bed. The ash material contained in the fins particulate material melts, and is conducted to the bubbling fluidized bed (31).
