Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Statistical Modification Model of Boiler Energy Efficiency

[0019] According to the current boiler load, steam drum pressure, outlet steam pressure, furnace temperature and exhaust gas temperature real-time collection, after a judgment period T 1 , under the condition that the boiler is relatively stable, the statistics of the current boiler energy efficiency η 1， Let η max =η 1， Increase the amount of fuel ∆F 1 , and then after a judgment cycle T 2 Finally, calculate the boiler energy efficiency η 2， If η 2 >η 1 Then η max =η 2； If η 2 1 Then η max =η 1 , after four consecutive judgment cycles, if η 2、 n 3、 n 4、 n 5 are less than η 1， Then η max =avg(η 1、 n 2、 n 3、 n 4、 n 5 ).

Abstract

The invention relates to the technical field of multi-boiler coordination optimizing control for header-system boilers and discloses a multi-criterion multi-boiler coordination control system based on the energy efficiency of boilers. The multi-criterion multi-boiler coordination control system based on the energy efficiency of the boilers is provided with a boiler energy efficiency statistics and correction module, a coordination optimizing control module, a fuel system advanced control module and a fuel regulation controller. By adoption of the multi-criterion multi-boiler coordination control system based on the energy efficiency of the boilers, the problems that pressure fluctuation of a pipe network in a header-system boiler system is large, coordination between the boilers is poor, and boiler efficiency cannot be used sufficiently due to mutual suppression of the boilers are effectively solved, and the boilers can operate more economically and efficiently.

Description

technical field [0001] The invention relates to the technical field of boiler optimization control, in particular to a multi-boiler coordinated optimization control system for boilers. Background technique [0002] With the advancement of science and technology and the rapid development of industry, boilers have become important power equipment in thermal power, chemical industry, metallurgy and other industries. In order to make the boiler run more safely, stably and economically, the quality and effect of boiler control are very important. Steam main pipe is one of the core devices for parallel operation of main tube boilers. The control effect of main pipe pressure directly affects the operation status and fuel utilization rate of the boiler. Large, the large load deviation between multiple boilers suppresses each other, resulting in energy waste, which has become the main research topic of the boiler system. Contents of the invention [0003] According to the charact...
