Voltage stabilizing protection control system of heavy oil burner

Abstract

The invention discloses a voltage stabilizing protection control system of a heavy oil burner. The voltage stabilizing protection control system comprises two temperature sensors arranged at an oil inlet and an oil outlet of the heavy oil burner, respectively, a comparator connected with the two temperature sensors simultaneously, a temperature control circuit connected with the comparator and the heavy oil burner simultaneously, and a voltage stabilizing circuit connected in series between the temperature control circuit and the comparator. The voltage stabilizing protection control system of the heavy oil burner is capable of controlling running of the whole heavy oil burner according to a temperature difference between a heavy oil going into the burner and the heavy oil ejected out of the burner, and also capable of automatically shutting down the heavy oil burner when the temperature difference is too large, and therefore, the use safety of the product is improved and the service life of the product is prolonged.

Description

technical field [0001] The invention belongs to the safety field of heavy oil burners, and specifically refers to a heavy oil burner voltage-stabilizing protection control system used on a carbon roaster. Background technique [0002] At present, the automatic combustion control systems of similar roasters at home and abroad mostly use heavy oil and other oils as fuel oil. Because these fuel oils are of low quality and mostly viscous, do not have good flow properties and optimal liquefaction state, when the burner injects fuel oil into the furnace, it is necessary to atomize the injected fuel oil In order to achieve a better heating and combustion effect. In order to meet this condition, it is necessary to heat these fuel oils, and the current conventional methods are mainly electric heating, and because the atomization of heavy oil needs to be heated to 110°C, this heating method can only be realized on the oil road, and Not easy to achieve in the burner area.

In order to meet this condition, it is necessary to heat these fuel oils, and the current conventional methods are mainly electric heating, and because the atomization of heavy oil needs to be heated to 110°C, this heating method can only be realized on the oil road, and Not easy to achieve in the burner area

[0003] Because electric heating cannot be used in the burner, the current automatic combustion control system of the roaster has the following deficiencies: First, the heated heavy oil in the oil circuit will still cool down after entering the burner, especially when there is too much When the branch burners are connected in series on the same oil path, the fuel oil passing through the burners from the head end to the end will still have a large degree of cooling, which will cause the heavy oil in the several burners at the end to be in a poor liquefaction state. As a result, the atomization effect of the injected fuel oil is poor or cannot be atomized, so that an oil line is formed and sprayed to the bottom of the furnace, resulting in a large temperature difference between the upper and lower sides of the furnace cavity, coking at the bottom of the furnace to block the fire path and burn the furnace body, affecting the quality of the product; Secondly, it will increase the consumption of fuel oil and increase the production cost; finally, due to poor atomization of fuel oil, it will also cause incomplete combustion, resulting in a large amount of heavy oil adhering to the flue, which is easy to catch fire, and the smoke emission is not up to standard
