Abstract

The invention discloses an efficient and safe low-calorific-value waste gas burner and belongs to the technical field of industrial low-calorific-value waste gas burning treatment waste gas burners. The efficient and safe low-calorific-value waste gas burner is mainly composed of an upper cone, a low-calorific-value burning device, a high-calorific-value burning device, a heat insulation layer, aheat storage layer and a lower cone. The efficient and safe low-calorific-value waste gas burner is characterized in that according to the burner, by arranging the heat insulation layer of a compositestructure and the multi-section turn-back-flow type heat storage layer, the upper cone, the lower cone, the low-calorific-value waste gas burning device and the high-calorific-value gas burning device are separately arranged, and it can be guaranteed that combustible waste gas and air are mixed and in contact with each other repeatedly and are ignited and burn out. The efficient and safe low-calorific-value waste gas burner has the beneficial effects that safe and efficient burning is achieved, and explosion caused by insufficient low-temperature (less than 650 DEG C) burning is avoided. Theefficient and safe low-calorific-value waste gas burner is stable in structure, easy and convenient to operate, efficient and safe.

Description

technical field [0001] The invention relates to the technical field of a combustion furnace for the combustion treatment of industrial low calorific value waste gas, in particular to the combustion of synthetic ammonia, methanol, hydrogen peroxide and other fine chemical products using the blowing air produced by a fixed-layer intermittent gas-making furnace and the high calorific value waste gas in the air. The combustion furnace produces high-temperature flue gas to provide conditions for subsequent waste heat recovery. Background technique [0002] The existing industrial waste gas with low calorific value (such as the blowing gas from the fixed-bed intermittent gas-making furnace in the nitrogen fertilizer plant) has low combustible components, low temperature, and low recycling value. Most manufacturers directly vent it, causing pollution to the environment and waste of resources. Due to the pressure of environmental protection, some manufacturers have newly built blowi...
