Because the combustion process of liquid fuel is more complicated than that of gas fuel, the traditional liquid fuel water heater has a complicated structure and a large volume, and is limited to certain extent in the occasions of vehicle-mounted application, field mobile application and the like.
Chinese patent with application number 201620988702.X discloses an instant heating type fuel oil water heater, and the type includes support, combustion tank, water pipe and oil tank, and combustion tank and oil tank setting are equipped with the combustion chamber on the support in the combustion tank, and the exhaust port and the oxygenating mouth with the combustion chamber intercommunication are seted up respectively to the upper portion and the bottom of combustion tank, are equipped with ignition needle and fuel sprayer in the combustion chamber, and the fuel sprayer communicates with the oil tank. Above-mentioned technical scheme has improved the defect that liquid fuel water heater structure is complicated, bulky among the prior art to a certain extent, provides a simple structure small fuel water heater who is fit for outdoor use, has positive meaning. However, the above technical solutions still have major drawbacks: the technical scheme of using an oil nozzle to atomize fuel oil and then burn the fuel oil belongs to diffusion type burning and is characterized in that the combustion process is longer, the flame contains tiny fuel oil fog drops before the fuel oil is completely burnt, the flame extinguishes when the fuel oil fog drops touch a burning tank with the temperature below the burning point of the fuel oil, smoke containing unburned fuel is generated, the burning efficiency is reduced, the smoke emission contains unburned hydrocarbon, and the environment is polluted.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a radiation type liquid fuel water heater, which adopts a radiator to heat water by a heat exchanger in a radiation heat transfer mode through partial heat energy released by a liquid fuel burner, so that fuel can be fully and efficiently combusted on the premise of keeping the characteristics of simple structure and small volume of the water heater, the efficiency is improved, and the environmental pollution is reduced.
The technical scheme provided by the invention is as follows: a radiant liquid fuel water heater comprising: the liquid fuel burner heats water by transferring part of heat energy released by combustion from the liquid fuel burner to the heat exchanger in a radiation manner.
Further, the heat exchanger is a gas-liquid heat exchanger.
Further, the radiator is disposed between the liquid fuel burner and the heat exchanger.
Further, the radiator is made of ablation-resistant materials.
Furthermore, the radiator is provided with a plurality of through holes towards the direction of the heat exchanger, and the through holes are used for guiding flame and high-temperature flue gas to the heat exchanger.
The working principle of the invention is as follows: the liquid fuel burner produces flame and high temperature flue gas when burning, and the temperature rises to the blazing state after some heat energy is absorbed by the radiator, and the blazing radiator transmits the heat energy to the heat exchanger by radiation mode, and then heats water by the heat exchanger. Because the incandescent radiator is arranged between the liquid fuel burner and the heat exchanger, the temperature of the incandescent radiator is higher than the burning point of the liquid fuel, tiny fuel oil fog drops and unburned hydrocarbon which are not completely burnt in flame and smoke generate baffling and intensified burning after being close to and contacted with the incandescent radiator, thereby greatly improving the burning efficiency, reducing the content of the unburned hydrocarbon in smoke emission and protecting the environment.
