摘要:
The invention concerns the area of combustion technology and relates to a device and a method, which can be used, for example, for the combustion of wood or coal in the domestic sector. The object of the invention is to provide a device which is technically simple and cost-effective, and with which a substantially continuous exhaust gas treatment can be carried out, with regards to the discontinuous working method of the single-chamber combustion system. The solution according to the invention consists of a device, wherein at least one component is arranged in the exhaust gas flow, which component entirely or partially consists of a catalytically effective material, and wherein at least one component is also arranged in the exhaust gas flow downstream of the component made of a catalytically effective material in the flow direction, which component consists of a material having a higher volumetric heat capacity than the component made of a catalytically effective material.

A gas turbine engine using a rich-lean catalytic combustion system includes a rich catalytic burner (24) and a lean catalytic burner (26). The rich catalytic burner (24) includes a rich catalytic reactor (28) and a heat exchanger (30). The rich catalytic reactor (28) catalytically bums a fuel rich mixture (34) to provide a heated fuel (36). The heat exchanger (30) receives a stream of air (A) that absorbs a portion of the heat from the catalytic burning of the fuel rich mixture (34) to keep the reaction in the rich catalytic reactor (28) at or below a threshold temperature. A resulting heated air (40) from the heat exchanger (30) and the heated fuel (36) are mixed in a mixing zone (42) to provide a heated fuel-air mixture (44). The lean catalytic burner (26) receives and bums the heated fuel-air mixture (44).

Proposed herein is a burner (20) for the combustion of hydrogen on a catalyst, comprising, in a body (21) of the burner (20) a first self - ignition catalyst (23) and a subsequent group of oxidation catalysts (26), as well as comprising a heat exchanger (35) heated by the burnt gases, wherein in the burner (20) the heat exchanger (35) is obtained as a common heat exchanger and it is arranged outside the body (21) of the burner (20) accommodating the catalysts (23, 26). A head (22) accommodating the self - ignition catalyst (23) may be separated by a body (40) accommodating the oxidation catalysts (26). A second heat exchanger, passed through by cold water, allows production of high purity distilled water. In the proposed boiler a first part accommodates the burner modules (20) and another part accommodates the common heat exchanger (35) and the possible additional heat exchanger for producing distilled water.

The invention relates to a catalytic radiating heating appliance that comprises at least one catalytic cell (11) including a catalytic combustion chamber (15) associated with a gas diffuser (16) supplied by an external supply source and adapted for diffusing a fuel gas on a catalyst (17a) on which is arranged a diffusion structure (17b) adapted for ensuring a substantially homogenous distribution of said fuel gas. The catalyst (17a) is adapted for oxidising hydrogen injected into the catalytic combustion chamber (15) and diffused by the gas diffuser (16). The appliance further includes a means (22) for controlling and monitoring the gas supply, a means (23) for controlling the inner temperature of the catalytic combustion chamber (15), and a means for generating a thermal radiation.
