Abstract
The utility model provides a gas current-sharing loop for the use of a fuel heater. The gas current-sharing loop is circular, on which is distributed with the gas current-sharing holes with various sizes. According to the area distribution of each gas current-sharing hole, along the direction of both sides of the gas current-sharing holes with the smallest size, the size of the gas-current-sharing hole is gradually increased. When in use, the gas current-sharing loop is installed between a heat exchanger and a burner in the fuel heater, which is fixed on an end of the gas flow outlet of the heat exchanger cavity of the fuel heater. On the gas current-sharing loop, the side of the gas current-sharing hole with the smallest size is disposed on the exhaust port side of the fuel heater, so that from the exhaust port side of the fuel heater to the side opposite to the exhaust port, the gas flow area of the fuel heater can be gradually increased. Thus during the process that the gas flows to the exhaust port, the total flow resistance of each gas flow path is equivalent in order to achieve the purpose that the gas can be in uniform flow in the entire channel to improve the thermal efficiency. With the utility model, the thermal efficiency of the fuel heater can be increased by 4 %.
Description
Technical field
The utility model relates to the combustion gas current equalizer that fuel heater is used, and belongs to the fuel heater technical field.
Background technology
Fuel heater is as a kind of independently heating plant, has been widely used in that various conveying mechanicals such as automobile, boats and ships are warmed oneself and engine prewarming etc. under low temperature environment.As the heat exchanger of fuel heater critical component, the height of its heat exchange efficiency has great influence to heat efficiency of heater and other performance.
At present, various types of fuel heater ubiquities combustion gas short circuit problem in various degree, promptly under the situation that fuel gas calorie is not fully absorbed by the heat exchanger in the heater, its high-temperature fuel gas just escaped into atmosphere by exhaust outlet by way of distance is near relatively by the little passage by heater exhaust outlet one side of flow resistance, and exhaust back pressure is more little, this phenomenon is serious more, thereby causes the unnecessary heat loss of fuel heater.
Summary of the invention
The utility model provides a kind of combustion gas is evenly flowed out along the exhaust passage at the existing deficiency of existing fuel heater, can improve the gas flow equalizing ring for oil heater of the fuel heater thermal efficiency.This gas flow equalizing ring can make the fuel heater energy savings, and parts such as heat exchanger in the fuel heater and burner are heated evenly, and improves the phenomenon of thermal stress distribution inequality.
Gas flow equalizing ring for oil heater of the present utility model adopts following technical solution:
This gas flow equalizing ring ringwise, be distributed with the equal discharge orifice of combustion gas that area varies in size on it, the area distributions of the equal discharge orifice of each combustion gas is that the area along the equal discharge orifice of two side direction combustion gas of the equal discharge orifice of combustion gas of area minimum increases the combustion gas current-sharing hole area maximum relative with the equal discharge orifice of the combustion gas of area minimum gradually.
Various geometries such as circular, the square or runway shape of being shaped as of the equal discharge orifice of combustion gas.
During use, gas flow equalizing ring of the present utility model is installed between the heat exchanger and burner in the fuel heater, gas flow equalizing ring can be fixed on the end face of heat exchanger inner chamber gas outlet of fuel heater by screw or rivet.The outer shroud shape of gas flow equalizing ring matches with the shape of heat exchanger inner chamber gas flow outlet in the fuel heater, and hole shape then matches with the outer shape of burner in it.A side of the area minimum of the equal discharge orifice of combustion gas is in the exhaust side of fuel heater on the gas flow equalizing ring, make exhaust side to its combustion gas circulation area of exhaust outlet opposite one side of fuel heater become big gradually, promptly the air-flow distance is short, little along the combustion gas current-sharing hole area on the gas flow equalizing ring of little place, the path correspondence of journey flow resistance in fuel heater, so that local flow resistance increases; Otherwise, the air-flow distance is long, big along the combustion gas current-sharing hole area on the gas flow equalizing ring of big place, the path correspondence of journey flow resistance in fuel heater, so that local flow resistance reduces, thereby make combustion gas in flowing to the process of exhaust outlet, total flow resistance of its each flow path equates, evenly flow in whole runner to reach combustion gas, avoid short circuit, improve the purpose of the thermal efficiency.
The utility model can make the thermal efficiency of fuel heater improve more than 4%.

The specific embodiment
As depicted in figs. 1 and 2, gas flow equalizing ring for oil heater 1 of the present utility model is a ring with inside and outside circle (or other geometry), is distributed with the equal discharge orifice 2 of some combustion gas that area varies in size on this ring.The area of the equal discharge orifice of each combustion gas on the gas flow equalizing ring 1 is to increase gradually to its both sides along the equal discharge orifice of the combustion gas of area minimum, with the relative combustion gas current-sharing hole area maximum of the minimum equal discharge orifice of combustion gas of area.The equal discharge orifice 2 of combustion gas can be various geometries such as circular, square or runway shape.The outer shroud shape of gas flow equalizing ring 1 matches with the gas outlet end surface shape of heat exchanger inner chamber in the applied fuel heater, and interior hole shape then matches with the outer shape of burner in the fuel heater.
The application of the utility model in liquid oil heater as shown in Figure 3 and Figure 4.Burner 3 in the liquid oil heater is installed in the heat exchanger 6, and gas flow equalizing ring 1 can be fixed on the end face of gas flow outlet in the combustion gas collection chamber 4 in the heat exchanger 6 by screw or rivet etc.The outer shroud shape of gas flow equalizing ring 1 matches with the shape of heat exchanger 6 inner chamber gas flow outlets in the liquid oil heater, and the interior hole shape of gas flow equalizing ring 1 then matches with the outer shape of burner 3.As shown in Figure 4, a side of the area minimum of the equal discharge orifice of combustion gas is in exhaust outlet 5 sides of liquid oil heater on the gas flow equalizing ring 1, make exhaust outlet 5 sides to its combustion gas circulation area of exhaust outlet opposite one side become big gradually, promptly the air-flow distance is short, little along the combustion gas current-sharing hole area on the gas flow equalizing ring 1 of little place, the path correspondence of journey flow resistance in liquid oil heater, so that local flow resistance increases; Otherwise, the air-flow distance is long, big along the combustion gas current-sharing hole area on the gas flow equalizing ring of big place, the path correspondence of journey flow resistance in fuel heater, so that local flow resistance reduces, thereby make combustion gas in the process that flow to exhaust outlet 5, total flow resistance of its each flow path equates, evenly flow in whole runner to reach combustion gas, avoid short circuit, improve the purpose of the thermal efficiency.
