Embodiment Construction
[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0016] It is difficult to increase the temperature of the steam boiler furnace due to its large space. In addition, the interior of the boiler furnace is full of evaporation water pipes that absorb heat. The temperature of the water in the water pipe directly affects the temperature of the furnace. If you want to increase the temperature of the furnace, you must first increase the temperature of the water in the water pipe, which also includes the temperature of the water in the steam drum, and the specific heat capacity of water is much larger than that of other substances, so steam It takes hours for the boiler to go from normal temperature to normal production temperature. The use of internal combustion combustion can solve this problem very well. The internal combustion b...

The embodiment of the present invention discloses a steam power boiler burner, which includes a combustion tube and a burner outer tube. The combustion gas flow control tube is arranged inside the burner outer tube, and the combustion gas flow control tube is connected to the combustion gas inlet tube. , a conical valve is set on the combustion gas flow control tube; a heating burner and a combustion-supporting gas inlet tube are also set on the outer tube of the burner; in this way, when in use, coal gas enters the In the combustion gas flow control tube inside the outer tube of the burner, the combustion gas flow control tube can control the gas intake, and when the gas passes through the conical valve on the combustion gas flow control tube, it can generate The umbrella-shaped air curtain is fully mixed and burned with the air introduced from the combustion-supporting gas inlet pipe, and the heating burner can keep the internal working state of the combustion pipe and the burner outer pipe stable.
Description
technical field [0001] The invention relates to a burner, in particular to a steam power generation boiler burner. Background technique [0002] For conventional steam power boilers, in order to increase the temperature of the furnace, a large amount of combustion-supporting air and gas are often blown into the furnace for combustion, which is prone to a phenomenon of excessive local temperature. In this situation, it is easy to cause an increase in the production of nitrogen oxides and dioxins, which is not conducive to the environmental protection requirements of the current high pressure situation. In order to avoid the occurrence of the above problems and make the combustion of air and gas more complete and complete, a steam power boiler burner is needed to solve this problem. Contents of the invention [0003] In order to solve the above technical problems, the embodiment of the present invention provides a steam power boiler burner, which can make the gas and the co...
