Abstract

The invention discloses an ignition and combustion-supporting device for a boiler. The ignition and combustion-supporting device is arranged on a central axis of an inner cavity of a boiler main body;the ignition and combustion-supporting device is composed of a base, ignition and combustion-supporting nozzles and brackets, wherein one ends of the brackets are fixedly connected with the four corners of the inner wall of the boiler main body, and the other ends of the brackets are fixedly connected with the base, the base is positioned below a horizontal plane formed by a burner nozzle, and the outer wall of the base is fixedly connected with the four ignition and combustion-supporting nozzles, and spraying openings of the ignition and combustion-supporting nozzles face the spraying direction of the burner nozzle; input pipelines for natural gas and oxygen and igniters for igniting the mixed gas formed by the oxygen and the natural gas are arranged in the ignition and combustion-supporting nozzles; the ignition and combustion-supporting nozzles spray the flame formed by the ignition into pulverized coal air flow to complete the ignition, and can assist the combustion by ejecting oxygen to the pulverized coal air flow; and the heat generated during the ignition and combustion-supporting process is used for heating the steam, so the energy utilization rate is improved.

Description

technical field [0001] The invention relates to the technical field of boiler ignition and combustion support, in particular to a device for boiler ignition and combustion support. Background technique [0002] Thermal power generation is a power generation method that uses the heat energy generated by combustibles during combustion and converts it into electrical energy through a power generation device. Due to China's abundant coal resources, thermal power generation is still an important way of generating electricity. A thermal power plant is a power facility that uses the thermal energy released by fossil fuel combustion to generate electricity, including all equipment, devices, and instrumentation devices for fuel combustion heat release, thermal energy conversion, and electrical energy output, as well as buildings and structures set up in specific places for this purpose And all the ancillary facilities related to production and life, there are mainly several types of...
