Abstract
A method and an apparatus for treating comminuted waste material the method comprising: •a) heating comminuted waste material in a heating chamber (28) using one or more heating means (40a-f) to generate a combustible gas •b) measuring or determining the temperature in the heating chamber; •c) comparing the measured or determined temperature in the heating chamber (28) with a predetermined temperature range; and •d) adjusting the amount of heat applied by the one or more heating means (40a-f) to the heating chamber (28) to maintain the temperature in the heating chamber within the predetermined temperature range.
Claims20
A method of treating comminuted waste material, the method comprising:
- a) heating comminuted waste material in a first, second and third zone of a rotatable heating chamber using one or more heaters to generate a combustible gas,
- b) measuring or determining the temperature in the first, second and third zone of the rotatable heating chamber;
- c) comparing the measured or determined temperature in the first, second and/or third zone of the rotatable heating chamber with a predetermined temperature range for each of the first, second and third zone;
- and
- d) adjusting the amount of heat applied by the one or more heaters to the first, second and third zone of the rotatable heating chamber to maintain the temperature in each of the first, second and third zone of the rotatable heating chamber within the predetermined temperature range for each of the first, second and third zone;
- wherein the first zone has a first temperature T1, the second zone has a second temperature T2 and the third zone has a third temperature T3 and wherein the second and third temperatures T2 and T3 are higher than the first temperature T1.
An apparatus for treating comminuted waste material, the apparatus comprising:
- a rotatable heating chamber for generating a combustible gas from comminuted waste material, the rotatable heating chamber comprising an inlet for the introduction of comminuted waste material into the rotatable heating chamber, an outlet for the egress of a generated combustible gas from the rotatable heating chamber;
- one or more heaters configured or configurable to heat, in use, the contents of a first, a second and a third zone of the rotatable heating chamber;
- one or more temperature sensors arranged or arrangeable to measure or determine the temperature in the first, second and third zone of the rotatable heating chamber;
- and a controller configured or configurable to compare a measured temperature of the first, second and third zone of the rotatable heating chamber with a predetermined temperature range and to adjust the amount of heat applied by the one or more heaters to maintain the temperature in the first, second and/or third zone of the rotatable heating chamber within the predetermined temperature range for each of the first, second and third zone;
- wherein the first zone has a first temperature T1, the second zone has a second temperature T2 and the third zone has a third temperature T3 and wherein the second and third temperatures T2 and T3 are higher than the first temperature T1.
