Description

Atmospheric boiler using fuel oil and gas

The utility model relates to a kind of water heater, particularly a kind of gerotor type fuel oil, gas water heater.

" the gerotor type fuel oil hot water boiler " of China Patent No. 91229889.8, form by body of heater, combustion chamber, burner, fire tube, flue, smoke-box, heat-insulation layer and control assembly etc., it is characterized in that the combustion chamber is located at the bottom of body of heater, between body of heater and the combustion chamber by water spacer, fire tube two ends in water tank are communicated with combustion chamber and smoke-box respectively, and feed pipe enters in the body of heater through the smoke-box preheating earlier again.It is earlier the water preheat in the feed pipe to be entered in the body of heater water tank again, and heat fully is absorbed, and pollutes light, good work environment, can realize advantages such as automation is unattended, and is safe and reliable.Its weak point be feed pipe in smoke-box, must cause smoke-box big, complex process in the manufacturing, raw material consumption are big, heat exchange area is little in the practicality, the thermal efficiency is not high enough.

The purpose of this utility model provide a kind of production technology simple, save material the normal pressure fuel oil that the heat energy utilization rate is high, gas water heater.

Task of the present utility model is finished as follows, it includes body of heater, burner, the combustion chamber, smoke-box, fire tube, flue and automatic water supply tank, it is characterized in that: body of heater is hollow cylinder, the middle part is the combustion chamber, it in the interlayer body of heater water tank, respectively there is a smoke-box at the body of heater two ends, smoke-box outer end, a left side is equipped with automatic combustor, right smoke-box outer end is equipped with pays water tank, be isolated into two parts up and down by smoke baffle plate in the right smoke-box, fire tube is distributed in the body of heater water tank, fire tube two ends, bottom are communicated with the lower space of left smoke-box and right smoke-box, the top fire tube is communicated with the upper space of left smoke-box and right smoke-box, flue is communicated with right smoke-box, and the body of heater outside has two to be communicated with body of heater water tank and the communicating pipe of paying water tank, and automatic water supply tank is communicated with the body of heater water tank and is installed in the body of heater top, also have one to be communicated with automatic water supply tank and the communicating pipe of paying water tank, the body of heater water tank is provided with delivery port and water return outlet.

Body of heater of the present utility model adopts samdwich hollow cylindrical, the combustion chamber is located at the body of heater middle part, surrounded by the body of heater water tank on every side, uniform fire tube in the body of heater water tank, dispose automatic fuel oil, air burner and automatic water supply tank, make its design more scientific and reasonable, heat energy is absorbed and used more fully, further improved the thermal efficiency, reached more than 88%.This stove is compact to design rationally, saves raw material.Automaticity height in the use need not the special messenger be operated, and is applicable to big and medium-sized cities high building heating, heat supply, also can be used for hotel, restaurant, receives the domestic hot-water supply of industrial and mining enterprises in one's power.

Below with reference to accompanying drawing embodiment of the present utility model is further described.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the B-B profile of Fig. 1.

The concrete structure of the utility model normal pressure fuel oil, gas water heater as shown in Figure 1 and Figure 2.Make the interlayer cylindrical furnace of a hollow with corrosion resistant plate or steel plate, the middle part is combustion chamber 1, it in the interlayer body of heater water tank 16, the body of heater two ends are welded with one and the sizable smoke-box 7 of furnace diameter respectively, 15, left side smoke-box 15 and body of heater are that same hollow interlayer is cylindrical, its outer end is equipped with automatic fuel oil, the automatic combustor 17 of gas, right smoke-box 7 outer ends install and fix a pair water tank 8 that diameter is identical with body of heater with several bolts, be separated into two parts up and down by smoke baffle plate 9 in the middle of the right smoke-box 7, fire tube 2 is distributed in the body of heater water tank 16, fire tube 2 two ends in bottom are communicated with the lower space of left smoke-box 15 and right smoke-box 7, top fire tube 2 is communicated with the upper space of left smoke-box 15 and right smoke-box 7, flue 10 is communicated with on right smoke-box 7 tops, and the body of heater outside has two to be communicated with body of heater water tank 16 and the communicating pipe 11 of paying water tank 8.Automatic water supply tank 14 is installed and is communicated with above body of heater water tank 16.Also have one to be communicated with automatic water supply tank 14 and the communicating pipe 13 of paying water tank 8.Whole body of heater is installed on the support 5, and the body of heater skin has insulation layer 4.Hot water outlet 12 is arranged at body of heater water tank 16 tops, and the hot water backwater's mouth 3 that cooled off is arranged at the bottom.

During work, automatic fuel oil, air burner 17 oil jetting combustions, flame is 1 internal combustion in the combustion chamber, the heat major part that it produced is directly absorbed by the water in the body of heater water tank 16, high-temperature flue gas, is got rid of by flue through dividing plate 9 tops of top fire tube 2 right smoke-boxes 7 by left smoke-box 15 to left smoke-box 15 through right smoke-box 7, bottom fire tube 2 again.So in fact, form circulation heating, the heat of burning is absorbed more fully body of heater water tank 16 and pair water tank 8.Pair water tank 8 of body of heater right-hand member is communicated with body of heater water tank 16 can increase heat exchange area to a greater extent, improves the thermal efficiency.

When heating was supplied water, hot water was supplied with radiator hot water by hot water outlet 12, and the water after heat radiation enters in the body of heater water tank 16 from water return outlet 3 again, forms circulation.

When water shortage, give 16 moisturizings of body of heater water tank automatically by automatic water supply tank 14, connect automatic water supply tank 14 and the communicating pipe 13 of paying water tank 8, except the moisturizing of payment water tank, also play open to atmosphere effect.
