Embodiment Construction

[0037] Combine below Figure 1 to Figure 6 The technical solution provided by the present invention is described in more detail.

[0038] see Figure 1 to Figure 3 , the embodiment of the present invention provides a combustion system, including a furnace 1 , a burner 2 , a first fuel system 3 and a second fuel system 4 .

[0039] The combustion system mainly includes a burner 2, a fuel system, and an air supply system. The fuel system is used to provide the fuel required by the burner 2 . There are two types of fuels: gaseous fuels and oily liquid fuels. The first fuel system 3 is used to supply fuel oil to the burner 2 . The second fuel system 4 is used to provide gas fuel to the burner 2, such as natural gas, liquefied petroleum gas and the like. The air supply system mainly refers to providing the main air required for combustion. In the field of combustion systems, it is also called secondary air. The various embodiments of the present invention do not relate to the...

Abstract

The invention discloses a combustion system and a boiler, and relates to the field of tobacco industry boilers. The combustion system and the boiler are used for optimizing the structure of a combustion system. The combustion system comprises a hearth, a combustor, a first fuel system and a second fuel system. The combustor is installed at an inlet of the hearth. The first fuel system is hermetically connected with the combustor and detachably connected with the combustor or the hearth; the first fuel system is used for introducing to-be-combusted fuel into the combustor. The second fuel system is hermetically connected with the combustor and detachably connected with the combustor or the hearth. The second fuel system is used for introducing to-be-combusted fuel gas into the combustor, wherein one of the first fuel system and the second fuel system is in a using state. According to the technical scheme, an atomizer of the first fuel system is protected against corrosion of vapor generated during combustion of natural gas so that the boiler end atomizer can maintain a good working state, two-purpose switching of oil and gas is achieved, and normal running is also achieved.

Description

technical field [0001] The invention relates to the field of tobacco industrial boilers, in particular to a combustion system and a boiler. Background technique [0002] The oil-fired boiler includes a furnace, a burner, a primary air duct, an ignition air duct, an atomizer and a secondary air duct. The combustion process is: the fuel is passed into the atomizer, and the atomizer is atomized into fuel spray. The atomized fuel is ignited and burned together with the acetylene gas for ignition and the primary air delivered by the ignition air pipe. After the combustion is stable, the secondary air is delivered through the secondary air pipe. The secondary air is used as the main air for combustion to provide the oxygen required for the combustion process of atomized fuel. [0003] The inventors have found that there are at least the following problems in the prior art: the fuel efficiency of the oil-fired boiler is relatively low, and the pollution is relatively serious. ...
