Discuss the burning rate of liquid in the electric heating reactor

Release date: 2019-09-19 04:28:29 Visits: 403

Xiaoyi introduces the burning speed of liquid in the electric heating reactor.

The burning rate of the liquid in the electrically heated reactor is industrially expressed in two ways: one is the mass of the reactor liquid per unit area and unit time, which is called the mass burning rate of the reactor liquid; the other is the internal unit time The height of the burning reactor liquid represents the linear velocity known as the reactor liquid combustion.

1. The higher the initial temperature of the liquid in the electric heating reactor, the faster the burning speed. The combustion rate of liquids in multi-component mixed reactors is usually fast and slow. For example, when crude oil, gasoline, kerosene, heavy oil, and other petroleum products are burned, low-boiling components with high burning rates are first evaporated. As the combustion progresses, the content of high-boiling components in the reactor liquid relatively increases, the relative density, viscosity, and flash point also increase relatively, the evaporation rate gradually decreases, and the combustion rate gradually decreases.

2. The liquid burning rate of the reactor depends on the evaporation of the liquid in the reactor, that is, the liquid burning in the reactor first evaporates and then burns. The liquid burning rate of the reactor is related to the initial temperature, heat capacity, latent heat of evaporation, and radiant capacity of the flame.

3. Non-aqueous flammable reactor liquids contain faster burning liquids than aqueous reactors, especially for the early stages of heavy petroleum products. If the reactor liquid is burned in the tank, the burning rate is also related to various factors, such as tank diameter, tank liquid level and liquid-gas contact area. Generally, as the diameter of the tank increases, the burning rate increases, and low-level combustion is faster than high-level combustion. At the same time, wind also has a certain effect on the speed of flame spread on the liquid surface. When the wind speed reaches a certain critical value, the combustion speed decreases, and even the flame is blown out.

The liquid burning rate of the electrically heated reactor also reflects the risk of liquid burning in the reactor, and the reactor has a low risk of liquid fire and it is easier to control the liquid in the reactor than in a fire situation.

Xiaoyi will introduce the burning speed of liquid in the electric heating reactor for you.


The burning rate of liquid in electric heating reactor is expressed in two ways in industry: one is the mass of reactor liquid burning per unit area per unit time, which is called the mass burning rate of reactor liquid; the other is the linear velocity of reactor liquid burning per unit time. Degree.


1. The higher the initial temperature of liquid, the faster the combustion rate. The combustion rate of liquid in multi-component mixing reactor is usually fast and slow. For example, when crude oil, gasoline, kerosene, heavy oil and other petroleum products are burned, the low boiling point components with high combustion rate are evaporated first. With the combustion proceeding, the content of high boiling point components in the reactor liquid increases, the relative density, the viscosity and flash point increase, the evaporation rate decreases and the combustion rate slows down.


2. The liquid combustion rate of the reactor depends on the evaporation of the liquid in the reactor, that is, the liquid combustion in the reactor evaporates first and then burns. The liquid combustion rate of the reactor is related to the initial temperature, heat capacity, latent heat of evaporation and radiation capacity of flame.


3. Non-aqueous flammable reactor liquids contain faster combustion liquids than aqueous reactor liquids, especially in the early stage of heavy petroleum products. If the reactor liquid burns in the tank, the combustion rate is also related to various factors, such as tank diameter , tank level and liquid-gas contact area. Generally, with the increase of tank diameter, the combustion rate increases, and the combustion at low level is faster than that at high level. At the same time, the wind has a certain influence on the flame spreading speed on the liquid surface. When the wind speed reaches a certain critical value, the combustion speed decreases, and even the flame is blown out.


The liquid combustion rate of the electrothermal reactor also reflects the risk of liquid combustion in the reactor, and the reactor has a low risk of liquid fire, and it is easier to control the liquid in the reactor than in the case of fire.
