Problems solved by technology

This causes the supply of fuel to be intermittent, because the fuel combustion method is intermittent, which makes the combustion system prone to blockage, coking, fire failure, non-combustibility, detonation, and even deflagration

Embodiment Construction

[0025] Referring to Fig. 1, the regenerative high-temperature air combustion device of the present invention includes a furnace body 8, on which at least one fuel nozzle 1 for injecting fuel and at least two burner bricks connected with the furnace body 8 are arranged. 4 connected at least two regenerators 2, the regenerator 2 blows combustion air into the furnace and induces flue gas in the furnace to store heat for the regenerator. Therefore, the fuel supply system and the heat storage system are separated from each other, the fuel is continuously supplied by the fuel nozzle 1, and the combustion-supporting hot air is alternately supplied by the two heat storage chambers 2 to ensure that the temperature of the hot air is 800°C (100°C lower than the furnace temperature) -200°C) or so.

[0026] see figure 2 , the combustion-supporting hot air fed into the regenerator 2 enters the combustion chamber through the through hole of the burner brick 4 . The upper plane of the thro...

Abstract

A heat storage high temp air combustion device includes a furnace body, with at least a nozzle spraying fuel and two heat storage chambers providing combustion supporting gas connecting with its mouth brick. The method is to supply fuel continuously in a same direction to the furnace and the supporting hot air and fuel enter into the furnace separately from each own channel to be mixed in the body and burnt, which can continuously spray fuel into the furnace with continuous and stable flame without blockage, coking, blow-off, not burning, detonation to save energy.

Description

technical field [0001] The invention relates to high-temperature air combustion technology, such as metallurgy, non-ferrous metals, glass, ceramic melting and other industries, in particular to a regenerative combustion device and method for high-temperature air combustion technology. Background technique [0002] The regenerative combustion method of the high-temperature air combustion technology for the melting of metallurgy, non-ferrous metals, glass, ceramics and other materials needs to continuously supply hot air to the furnace body. The existing regenerative high-temperature air combustion system has no less than two regenerators, two fuel combustion nozzles and corresponding matching valves. Each regenerator is interlocked with the fuel combustion nozzle inside, and the fuel, combustion-supporting air and exhaust gas are controlled by corresponding valves respectively. Figure 7 It is a schematic diagram of an existing regenerative high-temperature air combustion dev...
