Abstract

A full-automatic control system used for an oil-field heating furnace belongs to the oil industry automatic control technical field and adopts a PLC and a flow transmitter, an outlet pressure transmitter, a temperature transmitter, a flame detector, an air-gate actuator, an igniter, a gas-leaking detecting switch, a regulating valve, a main solenoid valve and a gas flow transmitter which are arranged in an internal part of the heating furnace to form an outlet temperature automatic control system, an air-gas proportioning control system, an automatic igniting system, a flame-out protection system, a flame-zone furnace-tube surface-temperature measuring system and a heating furnace efficiency automatic analyzing-calculating system, to successfully realize the steel tube surface temperature detection in the flame zone and to carry out the furnace tube surface temperature pre-alarming, alarming and furnace-stop control after the data processing by the PLC and also to realize a positive balance calculation control to the furnace efficiency through the measurement to the fuel flow, water flow and the water temperature of the inlet and outlet of the heating furnace, thus realizing the full automatic control to the heating furnace even without the observation of operators.

Description

Technical field: [0001] The invention relates to a fully automatic control system of an oilfield heating furnace, which belongs to the technical field of automatic control of the petroleum industry, in particular to the automatic control of each system of the oilfield heating furnace. Background technique: [0002] At present, there are many automatic control systems for heating furnaces in oil fields. Usually, the outlet temperature automatic control system consists of heating furnace outlet temperature detection elements and control valves; the control system consists of outlet pressure detection elements and regulating valves; Semi-automatic ignition system composed of solenoid valve. The above-mentioned systems are controlled by single-loop conventional instruments, and their control effects are limited. There are also some problems as follows, such as the inability to realize gas leakage detection in time, the inability to realize fully automatic monitoring and detectio...
