Title: Apparatus and method to improve pulverizer and reduce no_ emissions in coal-fired boilers
Inventor: BREEN BERNARD P
IPC: F23K1/04
Filed: 1993-05-11
Abstract: An apparatus and method to improve pulverizer operation and reduce nitrogen oxide emissions from furnaces which burn pulverized coal from at least one pulverizer. A duct type burner burns a fuel in the primary air which heats the primary air supplied to the pulverizers. The combustion increases the primary air temperature and improves the drying of the coal, thus improving the pulverizer throughput and/or the fineness of the pulverized coal. Operation of the duct burner also reduces the oxygen in the primary air. The reduction in oxygen reduces the propensity of the coal to ignite in the pulverizers and cause fires or even explosions.          The reduced oxygen in the primary air also reduces NOx formation.

Title: Process and device for producing leaven
Inventor: ISMAR THOMAS T
IPC: A21C1/00
Filed: 1992-05-30
Abstract: 57) Abstract A process for producing leaven and a de-vice especially suited to carrying out this process are to be improved in a way which ensures that a supply of leaven is constantly available in a quan-tity which can be predetermined and matched with the baking requirements, with only a modest technical outlay. This is accomplished according to the invention by placing the leaven preparation in an initial fermenter (2-4) in the fermenting chain and transferring it to the subsequent fer-menter when a specific cycle time (t1-t4), which is the same for all the fermenters, has elapsed. Once the dough has passed through all the fermenters in the chain, it is transferred to a storage container (5); the sum of the cycle times (t1-t4) equals the total time of passage (tR) of the leaven.
