Abstract

The invention discloses a full-premixing combustion device and a full-premixing combustion boiler. The full-premixing combustion device comprises a first combustor, a second combustor and an ignitionpin, wherein the first combustor is provided with a combustion face, the first combustor can input premixed gas and make the premixed gas to be combusted on the combustion face, the second combustor is provided with a gas output portion, the gas output portion of the second combustor is located on the upstream of the combustion face, the ignition pin is located on the downstream of the combustionface, and the ignition pin is used for lighting gas output by the gas output portion. According to the full-premixing combustion device and the full-premixing combustion boiler, the ignition structurecan be cooled reliably, and high-temperature failure of the ignition structure is avoided.

Description

technical field [0001] The present application relates to the field of combustion equipment, in particular to a fully premixed combustion device and a fully premixed boiler. Background technique [0002] The fully premixed combustion device is a device that combusts the combustible gas that is mixed in the premixed cavity of the fan. Part of the fully premixed combustion devices in the prior art, especially used in the field of fully premixed boilers, may include burners, fans, and ignition needles. After the combustible gas enters the burner, it is sprayed out from the fire hole on the side wall of the burner. [0003] In order to achieve ignition safety and avoid deflagration, the fully premixed boiler is usually equipped with a small fire for ignition. When the boiler starts to burn, first light a small fire on the ignition tube through ignition, and then the small fire of the ignition tube burns normally and stably, then feed the premixed gas into the burner and be ign...
