Combustor for fuel oil heater supplied with oil at multiple points

Abstract

The invention provides a combustor for a fuel oil heater supplied with oil at multiple points. The combustor comprises a combustion chamber cover, an oil absorbing lining net, a first-level combustion cylinder, a second-level combustion cylinder, a gas inlet flow guide cylinder, a gas inlet spiral-flow sheet, an oil supply pipe, an oil distributing branch pipe and an electric heating plug; the oil absorbing lining net is attached to the inner surface of the combustion chamber cover, and an oil distributing groove is arranged between the inner surface of the combustion chamber cover and the oil absorbing lining net; the outer surface of the combustion chamber cover is provided with an oil supply pipe, an oil distributing path and an oil distributing branch pipe, the inner surface thereof is provided with at least two oil distributing holes, the oil supply pipe is connected with the oil distributing path, the oil distributing path is directly connected with each oil distributing hole orconnected with the same by the oil distributing branch pipe, and the oil distributing hole is connected with the oil distributing groove between the inner surface of the combustion chamber cover and the oil absorbing lining net. The distribution of fuel oil is more uniform, which is beneficial for mixed combustion of oil and gas; the combustor has the characteristics of reliable and quick ignition starting, hard carbon deposit, low emission of harmful substance and high heat efficiency; the combustion efficiency of the combustor is more than 90%; and the economical efficiency can be increasedby more than 5%.

Description

technical field [0001] The invention relates to a burner for a fuel oil heater and belongs to the technical field of fuel oil heaters. technical background [0002] As an independent heating device, the fuel heater has been widely used for heating in low-temperature environments and engine preheating for various transport machinery such as automobiles and ships. As the core component of the heater, the combustion status of the fuel in the burner has a significant impact on the thermal efficiency of the heater and the emission of pollutants. In the existing evaporative burner, as disclosed in the Chinese patent document CN101280922 "a cone-shaped burner for a fuel heater", since it is a single-point fuel supply, although there are various fuel diversion and distribution measures, it is still To varying degrees, there is too much fuel in some parts of the oil-absorbing lining, which is not conducive to fully mixed combustion of fuel and air, thus affecting the improvement of ...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies of existing burners in fuel heaters, the present invention provides a burner for fuel heaters with multi-point oil supply, which has uniform distribution of fuel, sufficient mixing with air, low carbon deposition, high combustion efficiency and low emissions.
