MATRIX FOR REDUCED COMBUSTION VOLUME Russian patent published in 2011 - IPC F22B21/00 F23D14/02 

FIELD: heating.

SUBSTANCE: invention relates to energy industry and can be used in steam-generating boilers. The invention is aimed at generating sufficient heat energy to produce steam, ensuring accordingly an opportunity to obtain light and compact designs of boilers. Steam-generating boiler according to the first version contains a lot of steam pipes, an economiser located behind this set of steam pipes, and the fiery furnace located in front of a set of steam pipes and containing the inlet of oxidiser, intended for feeding the oxidiser, inlet of fuel intended for fuel supply, a set of steam pipes attached to the wall of the fiery furnace, and steam pipes are hydrodynamically connected to the steam chest located behind the fiery furnace, and a matrix for passive mixing of oxidiser and fuel. According to the second version, the boiler contains a set of steam pipes, an economiser located behind this set of steam pipes, and the fiery furnace located in front of a set of steam pipes, containing the first inlet of oxidiser, intended for filing of the first oxidiser, and the second inlet of oxidiser, intended for feeding of the second oxidiser, inlet of fuel intended to supply fuel, a set of steam pipes attached to the wall of a fiery furnace, and these steam pipes are hydrodynamically connected to the steam chest located behind the fiery furnace, and the first matrix for passive mixing of the first oxidiser and fuel, and the second matrix located behind the first one for passive mixing of the second oxidiser and fuel. Matrix generates a shorter outer zone of the flame combustion than a standard boiler.

EFFECT: reduction of volume of steam-generating boilers.
