Oil supply device of marine combustor

Abstract

The invention discloses an oil supply device of a marine combustor. The oil supply device comprises a heavy oil tank, a gasoline tank and a diesel oil tank. An output pipe of the diesel oil tank and an output pipe of the heavy oil tank are both connected to a first oil input three-way valve, a first conveying pipe is connected to the first oil input three-way valve, a first conveying pump is arranged on the first conveying pipe, and the first conveying pipe is connected with an oil input pipe of the combustor. An oil return pipe of the diesel oil tank and an oil return pipe of the heavy oil tank are connected with an oil return pipe of the combustor through a first oil return three-way valve. A first back pressure valve is arranged between the first conveying pipe and a first oil return pipe. An output pipe of the gasoline tank is connected with a second conveying pipe. The second conveying pipe is provided with a second conveying pump. The second conveying pipe is connected with the oil input pipe of the combustor. The input end of the second conveying pipe is connected with a second oil return pipe. The second oil return pipe is connected to the oil return pipe of the combustor.A second back pressure valve is arranged between the second conveying pipe and the second oil return pipe. The oil supply device has the advantages that the pressure in an oil input connecting pipe isstable, so that the combustion stability of the combustor is good.

Description

technical field [0001] The invention relates to the technical field of marine burners. Background technique [0002] An oil supply device for a marine burner usually includes: a heavy oil tank connected to a heavy oil delivery pipe and a heavy oil return pipe, the burner is provided with a burner oil inlet port and a burner oil return port, The heavy oil delivery pipe is connected to the oil inlet port of the burner, a heavy oil pump is arranged on the heavy oil delivery pipe, and the oil return port of the burner is connected with the heavy oil return pipe. [0003] The above-mentioned oil supply device is simple, but there are the following technical problems: 1. As the management of the marine environment becomes more and more stringent, the burner needs to burn different fuels in different sea areas to meet the discharge regulations of different sea areas. Obviously, the above-mentioned only heavy oil is used as The fuel supply unit cannot meet the demand. Second, the ...

Problems solved by technology

[0003] The above-mentioned oil supply device is simple, but there are the following technical problems: 1. As the management of the marine environment becomes more and more stringent, the burner needs to burn different fuels in different sea areas to meet the discharge regulations of different sea areas. Obviously, the above-mentioned only heavy oil is used as The fuel supply unit cannot meet the demand

2. The pipeline pressure is unstable, which affects the combustion efficiency

3. From the heavy oil tank to the burner, the pipeline is relatively long, which is inconvenient for maintenance and installation
