Embodiment Construction
[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings. The drawings and specific embodiments do not limit the scope of protection claimed by the present invention.
[0019] see figure 1 , which is a method for remote monitoring and diagnosis of energy consumption applied to tubular heating furnaces in the present invention, figure 1 The middle-tube heating furnace structure is the most common type in refining and chemical enterprises. It is equipped with a radiation section 1, a convection section 2 and an air preheater 10. The flue gas comes out from the convection section 2 and enters the air preheater 10 through the flue 6. 10 comes out and enters the chimney (not shown in the figure). figure 1 The middle-tube heating furnace is equipped with zirconia 3 , carbon monoxide analyzer 4 , thermocouple 5 , on-site data acquisition host 22 , central data processor 14 and display terminal 19 . According to the "Petro...

The invention discloses a method for remote monitoring and diagnosis of energy consumption of tubular heating furnaces in the fields of petroleum refining and petrochemical industry. It consists of the following steps: A. Every time at a certain interval, the on-site data acquisition host of each heating furnace is started, and the zirconia, carbon monoxide analyzer, and thermocouple send the flue gas out of the radiation section, convection section, and O of the air preheater. 2 Energy consumption data such as CO content, CO content and flue gas temperature are measured; B and N heating furnaces uniformly transmit the energy consumption test data to the central data processor of the device for data processing; C. The central data processor , convection section, air preheater O 2 Energy consumption index data such as content difference, flue gas temperature difference and CO content value. It is used to solve the problems that the existing technology adopts manual monitoring, cannot realize automatic monitoring of heating furnace energy consumption, has a long monitoring period, cannot optimize operation in time, and cannot automatically diagnose and manage energy consumption changes.
Description
technical field [0001] The invention relates to a heating furnace in the fields of petroleum refining and petrochemical industry, in particular to a method for remote monitoring and diagnosis of energy consumption of the heating furnace. Background technique [0002] Tubular heating furnace is a large energy-consuming household in petroleum refining and petrochemical industry production equipment. On the one hand, with the increase of human demand for energy, the CO caused by the combustion of heating furnace fuel 2 , SO x , NO x Emissions are increasing day by day. Therefore, improving the management level of heating furnace energy consumption is of great significance for reducing fuel consumption, reducing production costs, and reducing the emission of harmful gases to the atmosphere. With the development and progress of information technology, the powerful data processing capability of information equipment provides a good opportunity for traditional industries to imp...
