Abstract
The utility model provides a gas boiler, comprising a combustion apparatus and a heating water tank above the combustion apparatus, wherein, the heating water tank is covered with a preheating water tank, and the preheating water tank forms a saucer shape. The upper part of the preheating water tank is connected with the lower part of the heating water tank through a closed tube. A water inlet tube is connected with the lower part of the preheating water tank, and a water outlet tube is connected with the upper part of the heating water tank. The middle part of the preheating water tank is provided with smoke vents. A gas passage is arranged between the preheating water tank and the heating water tank. The utility model has the advantages of simple and compact structure, and high efficiency of the utilization of heat energy.
Description
The utility model relates to a kind of combustion apparatus.
The heating system in city progressively develops to the direction of central heating at present.But also have some areas can not realize central heating, need heating voluntarily, these regional residents adopt coal stove to warm oneself usually, and dust is big, and is seriously polluted.Both made in the zone of central heating, also existed the heat supply deficiency, situation about need warm oneself voluntarily.Natural gas, combustion gas such as liquefied petroleum gas have become city dweller's main fuel, but common gas furnace can not be used for heating.
The purpose of this utility model is to provide a kind of simple in structure, gas fired-boiler that heat utilization efficiency is high.
The purpose of this utility model is achieved in that it comprises burner, places the heating water tank of burner top, it is characterized in that: be covered with a preheating water tank in heating water tank, the preheating water tank is spill, preheating water tank's top is linked to each other by cross over pipe with the bottom of heating water tank, water inlet pipe is connected in preheating water tank's bottom, outlet pipe is connected in the top of heating water tank, and preheating water tank's middle part has venthole, is provided with exhaust gases passes between preheating water tank and the heating water tank.
Advantage of the present utility model is: the outside in heating water tank is covered with the preheating water tank; after the fuel combustion; at first the inwall with heating water tank carries out heat exchange; enter the exhaust gases passes between heating water tank and the preheating water tank then, carry out the secondary heat exchange, go out the venthole on the preheating water tank again with preheating water tank's the inwall and the outer wall of heating water tank; the absorption rate of heat is higher; if heating water tank is spill, have the good fiery effect of holding together, further improve the utilization rate of heat.The utility model is realized Natural Circulation by the density contrast between the hot water or cold water, and is simple in structure, can be as the uses such as heating voluntarily of family or small size unit.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an external structure schematic diagram of the present utility model.
For example the utility model is done more detailed description below in conjunction with accompanying drawing: burner 1 is fixed on the support 13,2 of heating water tank are in the top of burner, preheating water tank 5 covers on outside the heating water tank, preheating water tank and heating water tank all are spill, between preheating water tank and the heating water tank exhaust gases passes is arranged, preheating water tank's top is linked to each other by cross over pipe 10 with the bottom of heating water tank, water inlet pipe 9 is connected in preheating water tank's bottom, outlet pipe 8 is connected in preheating water tank's top, preheating water tank's middle part has venthole, flue 7 is installed on the venthole, has multi-disc heat collecting sheet 3 at the inwall of heating water tank, has multi-disc heat collecting sheet 4 at preheating water tank's inwall.
