The invention discloses a full premixing device for channel fuel gas air, comprising a fuel gas system, a combustion air system and more than one premixer, wherein the premixer comprises an air inlet arranged at the bottom of the premixer, a fuel gas inlet arranged at the middle part of the premixer, a spray gun branch pipe arranged in the premixer, and a mixed gas outlet arranged on the top of the premixer and communicated with a channel heating zone through a mixed gas pipeline; the fuel gas system comprises a fuel gas pressure regulating unit, a flow measurement unit, a security unit, a fuel gas sub-air package, more than one zoning fuel gas pipeline and more than one heating section fuel gas regulating unit, the zoning fuel gas pipelines are connected with the fuel gas inlet; and the combustion air system comprises more than one fan, an air pipeline arranged at a fan outlet, a gas busbar arranged on the air pipeline and more than one zoning air pipeline. Compared with the prior art, the full premixing device has the advantages that: 1, full automatic control is realized and labor intensity for workers is reduced; 2, fuel gas and air are evenly mixed to fully burn without discharging toxic gases; and 3, the security system is additionally arranged to the whole device to improve the security of the full premixing device.
Description
technical field [0001] The invention relates to a gas-air full premixing device for a forehearth, which is used for completely premixing gas and air for heating glass liquid in a glass melting forehearth, and belongs to the technical field of gas combustion equipment. Background technique [0002] When using a glass furnace for heating, it is necessary to pre-mix air into the gas. The utility model patent No. 00260216.4 published by the China International Intellectual Property Office introduces a fully premixed combustion device for air injection gas, which includes a combustion head, a combustion chamber, and an ignition Probe, injection device, proportional valve, regulating valve, fan and air valve, etc. The fan and air valve are upstream of the combustion equipment, the combustion head is located at the entrance of the combustion chamber, and the proportional valve is set on the side of the burner. The mixing pipe of the injection device is connected with the regulating...
