Energy-saving combustion control system for material loading and picking process of trolley type heat-treatment furnace

Abstract

The invention relates to a heat-treatment furnace and a combustion system thereof, in particular to an energy-saving combustion control system for the material loading and picking process of a trolley type heat-treatment furnace. The system comprises a furnace roof transmission mechanism, a furnace door, a trolley, a furnace door counterbalance, a contact inductor, an upper contact, a lower contact, an industrial computer, combustion systems, a signal input wire and a signal output wire, and is characterized in that the furnace door, the trolley, the furnace door counterbalance and the contact inductor are linked to one another; the contact inductor is in contact with the upper contact or the lower contact according to the open state of the furnace door; the upper and the lower contacts are connected with the signal input wire which is connected with the industrial computer; and the industrial computer controls the combustion systems through the signals. According to the invention, excessive fuel loss can be avoided, so as to effectively reduce the fuel consumption, save energy, increase industrial production output value and improve the comprehensive economical benefits; and meanwhile, the generation of pollution gases, such as CO2, SOX, NOX, and the like can be reduced, so as to reduce the discharge of those, and achieve the purpose of protecting environment.

Description

Technical field: [0001] The invention relates to a combustion system of a heat treatment furnace, in particular to a trolley-type heat treatment furnace energy-saving combustion control system during loading and unloading. Background technique: [0002] With the development of the economy, people have higher and higher requirements for the control of the combustion process, not only to have higher fuel combustion efficiency to achieve the purpose of saving energy, but also to reduce CO as much as possible. 2 and SO X , NO X Emissions of polluting gases, in order to achieve the purpose of protecting the environment. However, the existing trolley-type heat treatment furnace does not control the combustion process in the loading and unloading process. During the opening period of the trolley-type forging heat treatment furnace, the furnace door is raised and the trolley is pulled out. Due to temperature loss, the temperature in the furnace will suddenly increase. After the t...

Problems solved by technology

However, the existing trolley-type heat treatment furnace does not control the combustion process in the loading and unloading process. During the opening period of the trolley-type forging heat treatment furnace, the furnace door is raised and the trolley is pulled out. Due to temperature loss, the temperature in the furnace will suddenly increase. After the thermocouple senses the temperature, the low temperature signal is fed back to the industrial computer. Since the temperature cannot meet the set process temperature at this time, the industrial computer outputs a temperature rise signal, so it will automatically increase the fuel flow rate. The furnace door is still open, and the forgings are not in the heating area. Increasing the flow rate has no effect on heating the forgings, resulting in a great waste of energy.
