Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] As shown in Figure 1 and 2.

[0025] A chemical industrial heating furnace using coal water slurry as fuel, comprising a furnace body 10, the lower part of the furnace body 10 is connected with an ash hopper 9, and the furnace body 10 is provided with a combustion chamber 2 and a radiation section 3, and the combustion chamber 2 is located below , the radiant section 3 is on the top, and four or more (such as 6, 8, 10, etc., etc., the specific number should depend on the inner diameter of the furnace body 10) are arranged in a tangential circle on the body of furnace 10 around the combustion chamber 2. The coal-water slurry burner nozzle 1 that sprays the coal-water slurry into the combustion chamber is calculated and determined by calculating the temperature required for combustion. In the radiant section 3, there are vertical heat pipes 4 that ...

Abstract

The invention discloses a heating furnace for the chemical industry taking water-coal slurry. The furnace is a radiation-convection vertical drum furnace with vertical pipes, the burners arranged in layers at sides are in tangent circle combustion way, the heat strength along the length direction in the vertical pipe in the radiation section can be controlled well, is good for enhancing the convection heat transmission in the radiation chamber, this can supplement the radiation heat transmission weakened at the pipes at upper part of the furnace. A compact structure form with parallelly arranged radiation section and convection section is employed, which is useful for reducing the height of the heating furnace, reducing the equipment cost and good for safety in manufacturing.

Description

technical field [0001] The invention relates to a heating furnace, in particular to a heating furnace commonly used in the chemical industry, in particular to a chemical industrial heating furnace with coal-water slurry as the main fuel. Background technique [0002] At present, most of the fuels commonly used in heating furnaces in the petrochemical industry are high-sulfur oils such as residual oil and heavy oil. The use of such high-sulfur fuels has caused the heating furnace to emit sulfur dioxide into the atmosphere exceeding the standard, which seriously pollutes the surrounding environment of the factory and poses a threat to environmental protection. and pollution control has brought great pressure. At the same time, as the world crude oil price is rising day by day, the price of fuel oil will also rise accordingly, and the oil price will remain at a high level for quite a while, and the production cost of the petrochemical industry will continue to increase. Optimi...
