Abstract
The utility model relates to a gas water-heating boiler. A separation box is arranged between heat exchange tube bundle chambers, one end of the separation box is penetrated through a boiler furnace and is fixed on a boiler wall, a space is arranged between the other end of the separation box and the boiler furnace, an outer wall of a heat exchanger tube is provided with a heat absorption grid. Because the heat exchange path is extended, and the heat exchange rate is improved, the gas exhaust temperature is lower, and energy can be saved. The utility model has the advantages of safe operation, and convenient operation.
Description
The utility model relates to a kind of vertical gas-fired water heating boiler.
The purpose of this utility model just provides a kind of gas-fired water heating boiler that prolongs the heat exchange approach, improves rate of heat exchange, thus energy savings.
Its heat-exchange tube bundle of existing vertical boiler directly is communicated with water jacket, and the boiler hot switching channel of this structure is short, and heat can not fully be absorbed by heat-exchange tube bundle, and exhaust gas temperature is higher, wastes energy.
The purpose of this utility model is achieved in that a kind of gas-fired water heating boiler, comprise water jacket, flue, water inlet, delivery port, fire door etc., in flue, be provided with the heat-exchange tube bundle chamber from top to bottom successively, be provided with cell between heat-exchange tube bundle chamber and the heat-exchange tube bundle chamber, be provided with cell 9 between heat-exchange tube bundle chamber and the heat-exchange tube bundle chamber, be provided with cell between heat-exchange tube bundle chamber and the heat-exchange tube bundle chamber; One end of cell passes flue and is fixed on the furnace wall, and the other end and flue are provided with the gap, and an end of cell 8 and cell 4 is fixed on a side of furnace wall, and an end of cell 9 is fixed on a corresponding side of furnace wall.
The outer wall of heat-exchange tube is provided with the heat absorption grid.
On fire door, be provided with water jacket, be communicated with the water jacket of boiler by flexible pipe.
On cell, be provided with soil cleaning port.
The utility model is owing to prolong heat exchange approach, raising thermal conversion rate, and exhaust gas temperature is lower, thus energy savings; And it is safe and reliable to operation, easy and simple to handle.
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is the A-A cutaway view of Fig. 1,
Fig. 3 is the B-B cutaway view of Fig. 2.
Wherein: 1-boiler water jacket, 2-flame export, 3,5,6,7-heat-exchange tube bundle chamber, 4,8, the 9-cell, the 10-flue, 11-furnace shell, 12-flue base plate, 13-bottom water, 14-boiler bottom plate, 15-exhaust opening, the 16-water inlet, 17-water jacket, 18-delivery port, 19-heat-exchange tube, the 20-grid that absorb heat, 21, the 22-flexible pipe, the 23-fire door, 24-observation panel, 25-burner flange.
Below in conjunction with drawings and Examples the utility model is further described.
As shown in the figure, be provided with four heat-exchange tube bundle chambers from top to bottom successively in flue, heat-exchange tube bundle is communicated with cell, and combustion heat flow point is not divided into four zones, and prolong the heat exchange approach, improve rate of heat exchange, for strengthening heat absorption capacity, the outer wall of heat-exchange tube 19 is provided with heat absorption grid 20.Be provided with cell 8 between heat-exchange tube bundle chamber 7 and the heat-exchange tube bundle chamber 6, be provided with cell 9 between heat-exchange tube bundle chamber 6 and the heat-exchange tube bundle chamber 5, be provided with cell 4 between heat-exchange tube bundle chamber 5 and the heat-exchange tube bundle chamber 3; One end of cell passes flue and is fixed on the furnace wall, the other end and flue are provided with the gap, one end of cell 8 and cell 4 is fixed on a side of furnace wall, one end of cell 9 is fixed on a corresponding side of furnace wall, the cell decapacitation forces outside the hot-fluid folding row, water temperature in can also the homogenizing heat-exchange tube bundle prevents that gas is stifled.On fire door 23, be provided with water jacket 17, be communicated with the water jacket of boiler by flexible pipe 21, flexible pipe 22.On cell, be provided with soil cleaning port.
