Title:
COMBUSTION CONTROL METHOD AND DEVICE OF OXYGEN COMBUSTION BOILER
Document Type and Number:
WIPO Patent Application WO/2007/061106
Kind Code:
A1
Abstract:
Combustion control method and device of an oxygen combustion boiler capable
of controlling combustion constantly and easily by easily being applied to an
existing air combustion boiler. Oxygen in a set amount corresponding to a boiler
load instruction (35) is supplied to a boiler body (4), a boiler collected heat
quantity is measured from the inlet temperature of feed water supplied to the
boiler body (4) and the outlet temperature of steam, and the re-circulated flow
rate of combustion exhaust gas (14a) is controlled so that a collected heat quantity
(41) by the boiler body (4) is equal to a target collected heat quantity (42), whereby
an oxygen concentration in the whole gas introduced to the boiler body (4) is regulated.
