Problems solved by technology

[0009] In order to solve the problems of the prior art, the present invention proposes a new type of heating furnace with a multi-hearth structure. When the heating furnace tube in one furnace is affected by factors such as corrosion, coking and blockage, the operation is automatically or manually switched to another furnace. Realize continuous operation, which fundamentally solves the problem of device shutdown caused by coking of the furnace tube

Embodiment

[0035] This example figure 1 As shown, it is applied to residuum heating. The furnace body includes A furnace 3 and B furnace 4; the burner 2 is a strong mixed burner, including a combustion gas feed port 12, which can heat both furnaces. Each furnace is respectively provided with A furnace furnace tube differential pressure gauge 8 and B furnace furnace tube differential pressure gauge 9 between the inlet and the outlet, and between the inlet of the furnace body and the feed pipeline 1 is a feed space 13, That is, the space in the furnace body between the burner 2 and the two furnaces, the material to be heated first enters the feeding space 13 after entering the furnace body from the feed pipe 1, and the entrance of each furnace includes adiabatic, openable and closed A furnace switching board 10 and B furnace switching board 11, when the switching board is opened, the material enters the corresponding opened furnace from the feeding space, and each furnace includes A furna...

Abstract

A novel heating furnace with a multi-hearth structure comprises a feeding pipeline, a combustor, a furnace body and outlet pipelines, wherein the one combustor is disposed, and at least two hearths are disposed inside the furnace body; a switchable heat-insulated switch plate is disposed at the entrance of each of the hearths; a remote-transport differential pressure gauge is respectively disposed between the entrance and the exit of each of the hearths; feeding space is disposed between the combustor and the hearths, and the feeding pipeline enters the feeding space; and each of the hearth respectively comprises the outlet pipeline, and heat-insulated filler is disposed between the adjacent hearths. Without changing configuration and material of a furnace tube and quantity of the combustor, the novel heating furnace with the multi-hearth structure provided by the invention can be timely switched to heating of the other hearth when one of the hearths fails, does not need to conduct parking overhauling of the whole heating furnace, prolongs duration for the device parking caused by the overhauling of the heating furnace, increases operational stability of the device, does not need to dispose more standby furnaces and greatly reduces cost.

Description

technical field [0001] The invention relates to a novel heating furnace with a multi-hearth structure, which belongs to the fields of petrochemical and coal chemical industries. Background technique [0002] Heating furnace is a kind of heating equipment widely used in petroleum, chemical industry, metallurgy, electric power and natural gas industries. Its function is to use oil or gas as fuel to heat oil or other media. To meet the temperature requirements of downstream equipment for process streams. In the petrochemical industry, tubular heating furnaces have been widely used as a heating means to provide heat energy for petrochemical production. [0003] Tube heating furnace generally consists of five parts: radiation chamber, convection chamber, waste heat recovery system, burner and ventilation system. Furnace tubes are installed in the radiation chamber and the convection chamber, and this part is directly subjected to flame grilling, and the temperature is the highe...
