20110073048 | PRESSURE GAIN COMBUSTION HEAT GENERATOR - Disclosed herein is an efficient heat generation device where fuel is burnt in a pressure gain combustion process. The heat generating system has an inner combustion chamber that is housed in heat exchangers. The combustion chamber walls, in one form, include fluid conduits. While different fluids could be utilized, water is most common and the term water herein is intended to define water and all functional equivalents. The water conduits (tubes) may be multi-pass longitudinal, parallel to the combustor axis or they may be winded around the combustion chamber in a spiral fashion. The combustion products exiting the combustion chamber enter the outer liner where water tube bundles extract the heat of the combustion. One embodiment also utilizes an air preheating stage. Heated water and steam generated in the heat exchanger stages wrapped around the combustor enters the final heating stage where it passes through the flame accelerators in the combustion chamber. The flame accelerators within the combustion chamber are in the hottest region in the combustor and therefore exchanging heat at high temperatures increases the efficiency of the steam generation cycle. It also increases the produced steam quality. | 03-31-2011 |
