Increasing Productivity of the Boiler by Eliminate the Limited Capacity of the Thrust and Blow

Abstract

A new highly informative method of ²flow structure visual diagnostic², which allows you to identify the distribution of flow velocities actual values in flow parts. Solving problems experience in flow parts improving showed that today to analyze the efficiency it's uses only the effectiveness measure of the basic elements – pumps or fans, and the hydraulic resistance meanings in the equipment flow parts. To analyze of the flow structure improving results it was developed the effectiveness measure of equipment in general and its individual elements, and it was developed the system effectiveness measure for hydraulic and aerodynamic systems. Visual diagnostics gives us the opportunity to develop a new energy-saving technology, which allows to improve existing equipment, or to design the new one. More than 20 projects have already completed using energy-saving design technology FSTD. In these projects it was solved the problems of equipment productivity increasing, cleaning quality improving, noise or vibration reduction. Besides in all projects it was provided a significant reduction of energy consumption for own needs. Improving equipment blow paths two boilers KVGM-58 (Ilichevsk, Ukraine) has allowed them to increase the heat output of the boiler №3 from 36.2 to 51.93 MW and boiler №4 from 37.8 to 48.28 MW. Besides energy costs for operation of the blow fan are reduced by more than 40%.
