Thick oil heating furnace

Abstract

The present invention provides a thick oil heating furnace which comprises a burning stove, wherein the burning stove is provided with a smoke outlet. The smoke outlet is communicated with a Laval nozzle thermoregulator. The Laval nozzle thermoregulator is provided with an air inlet interface, a heating interface and a throat positioned between the air inlet interface and the heating interface. The air inlet interface is communicated with a blower. The heating interface is communicated with a heating device. According to the plan of the invention, the effect of the invention to the prior art is obvious. Through the Laval nozzle thermoregulator, the thick oil heating furnace of the invention organically combines the vacuum degree requirement required for preventing the smoke reflux by the heating furnace with the requirement of blending cold air for reducing the temperature of tube wall of heating device. The requirement can be obtained only through one air feeder. One air feeder can be saved. The thick oil heating furnace further has the advantages of simple operation maintenance, convenient and quick operation, electricity saving, energy saving, reduced production cost and increased economic benefit.

Description

technical field [0001] The invention relates to an industrial heating boiler, in particular to a heavy oil heating furnace. Background technique [0002] With the depletion of non-renewable petroleum resources and the rapid increase of the demand for petroleum products due to the rapid economic development, the heavy oil recovery technology based on thermal drive is more and more widely used. The extracted heavy oil has a high kinematic viscosity at normal ambient temperature, which is not conducive to the implementation of subsequent petrochemical technology. For this reason, the petrochemical department has designed various industrial heating boilers to heat the heavy oil to reduce the kinematic viscosity of the heavy oil, thereby reducing the movement resistance of the heavy oil, and enabling the subsequent petrochemical process technology to be implemented. There are three types of heavy oil heating furnaces widely used in oilfields: [0003] The first type is a heavy ...

Problems solved by technology

The electric heating furnace does not need to be equipped with a blower and an induced draft fan, nor does it need to control the heating temperature through the air excess coefficient. It only needs to control the heating power to control the heating temperature. The operation control and maintenance are relatively simple, and there is no pollutant emission, which saves precious Oilfield associated natural gas does not need to be supplemented with industrial circulating water of a certain purity; however, electric heating furnaces need to use more precious electric energy, and the power consumption is very considerable, which is not conducive to the optimization of energy consumption structure, and also increases the operating cost of petrochemical enterprises
