Background
At present, natural gas which can be used in the initial stage of oil field exploitation can be used as fuel in the application scene of the heat medium boiler, but as the supply of natural gas is insufficient in the later stage of oil field exploitation, crude oil must be used as main fuel, and diesel oil is used as emergency fuel supply. The burner matched with the offshore oil fixed platform heat medium boiler adopts three fuels, and can work by using natural gas, diesel oil and crude oil as fuels. The burner must operate by igniting the pilot gun with natural gas first and then igniting the main fuel (natural gas, diesel or crude oil) with the open flame of the pilot gun. Because the production process system is not put into operation at the initial stage of project construction, no fuel gas and crude oil can be supplied in the system, and only diesel oil is supplied, the ignition under the working condition of the initial cold state becomes a key problem. In order to ensure the smooth ignition of the heat medium boiler under the cold state condition, a fuel gas cylinder, a pressure reducing valve, a three-way valve and the like are added on one path of a boiler gas ignition system, and when the heat medium boiler is started at the cold state, external fuel gas is used for ignition in advance, and then main fuel diesel is ignited. Therefore, the problem of cold start of the thermal medium boiler is solved, and smooth ignition can be ensured under the condition that crude oil is used as main fuel because the production is stopped for maintenance or no natural gas is generated in the later period of oil field exploitation.
