Description
Technical Field
The utility model relates to a heart-shaped recombustion chamber of horizontal boiler belongs to boiler technical field.
Background
In energy conversion equipment for burning petrochemical fuels, natural gas, biomass gas fuels and coal-to-gas, a horizontal internal combustion shell type oil-gas boiler is widely applied due to high thermal efficiency. In the structural form of the horizontal internal combustion shell type oil and gas boiler, a flashback chamber in the structure is mainly in a round table (column) type with a traditional structure. The combustion-back chamber with the circular truncated cone-shaped structure can cause great waste to the space on two sides of the furnace pipe, reduces the arrangement quantity of the heat exchange pipes and reduces the heat exchange efficiency; in addition, the space in the upper part of the boiler shell is occupied, and the height of the steam space above the boiler shell is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a heart-shaped flashback chamber of horizontal boiler is provided to above-mentioned prior art, its compact structure, low in production cost, the heat exchange tube position is arranged rationally, has increased arranging quantity of heat exchange tube, has improved heat exchange efficiency.
The utility model provides a technical scheme that above-mentioned problem adopted does: the heart-shaped reburning chamber of the horizontal boiler comprises a front tube plate and a rear tube plate, wherein a side plate is arranged between the front tube plate and the rear tube plate, a furnace pipe connecting hole is formed in the front tube plate, a plurality of first tube bundle holes are uniformly formed in the left side and the right side of the furnace pipe connecting hole, a burner connecting hole is formed in the rear tube plate, and a plurality of second tube bundle holes are formed in the periphery of the burner connecting hole.
Optionally, the front tube plate, the rear tube plate and the side plate form a flashback chamber cavity, and the flashback chamber cavity is integrally heart-shaped.
Optionally, the side plate includes an upper horizontal segment and a lower circular arc segment, and the upper horizontal segment and the lower circular arc segment are connected through a left circular arc connecting segment and a right circular arc connecting segment.
Optionally, the central height of the burner connecting hole is lower than that of the furnace pipe connecting hole.
Compared with the prior art, the utility model has the advantages of:
1. the heart-shaped reburning chamber of the horizontal boiler has compact structure, low production cost and reasonable arrangement of the heat exchange tubes, increases the arrangement quantity of the heat exchange tubes and improves the heat exchange efficiency;
2. the utility model relates to a heart-shaped flashback chamber of horizontal boiler, it has reduced upper and lower direction height, has reduced the boiler casing inner upper portion space that occupies, has increased the height in top steam space.
