Optimizing and guiding system for coal-burned industrial boiler operation

Abstract

A coal-fired industrial boiler operating optimizing and guiding system in the field of energy-saving technology is provided, which comprises: a data communicating interface, a data processing module, a system display module, a boiler real-time efficiency processing module and an operation optimize and guide module; wherein, the data communicating interface accepts real-time operating data from a boiler control system and transfers to the data processing module which can check and filter the data received; the boiler real-time efficiency processing module processes and achieves the heat lose of boiler smoke discharge and incomplete physical burning and boiler real-time efficiency and then transfers to the operating optimize and guide module and the system display module to compare the upper limit value with the lower limit value of real-time air coal and the best air coal of the boiler; meanwhile, compare the temperature high limit of smoke discharged surveyed with that of the boiler and transfer the result to the system display module as well as send out operating and guide operational command; the system display module is responsible for displaying data. The invention is able to improve the efficiency of boiler.

Description

technical field [0001] The invention relates to a system in the technical field of energy saving, in particular to a coal-fired industrial boiler operation optimization guidance system. Background technique [0002] For existing coal-fired industrial boilers, due to different coal types and different furnace types, the boilers will not operate under the design conditions during actual operation, so the operating efficiency of the boilers will vary greatly. At present, the operation of industrial coal-fired boilers is completely based on the personal experience of the operators. The operation is very random, and the actual operating efficiency of industrial boilers is generally low. At present, the instruments installed for the inspection of coal-fired industrial boilers can only show the changes in the operating parameters of the boilers, but cannot reflect the actual operating efficiency of the boilers and the size of various losses. The boiler control system also only pla...

AI Technical Summary

Problems solved by technology

In addition, its shortcoming is that it does not solve the problems of real-time efficiency processing of coal-fired boilers and corrections after fuel calorific value changes. The energy loss analysis is based on the deviation of key parameters from the reference value, and the reference value of key parameters under different operating conditions It is difficult to determine, and the operation guidance obtained from this is not very operable for coal-fired boilers
