INTRODUCTION
AMONG ALL TYPES OF ENERGY THERMAL ENERGY PLAYS A KEY ROLE
THE SAFETY AND EFFICIENCY OF RUNNING THE THERMAL POWER PLANTS ARE VERY IMPORTANT
THE TYPE OF COAL IS MADE SURE THE POWER PLANT SYSTEM CAN BE CONTROLLED WELL
BUT IDENTIFICATION OF THE COALS ONLINE IS HARD ESPECIALLY FOR THE BLENDED COALS
3 FLAME INFORMATION INCLUDING AVG,STD DEV AND OSC FRE ARE EXTRACTED BY A FLAME DETECTOR
USING THIS DATA FLAME FEATURE MATRIXES ARE FORMED
BY CALCULATING THE CORRELATION COEFFICIENT OF THE MATRIXES BOTH SINGLE COALS&BLENDED COALS CAN BE IDENTIFIED WELL

1. DROP TUBE FURNACE
CAN BE DIVIDED INTO TWO SECTIONS IGNITION SECTION &BURNOUT SECTION
IGNITION SECTION1. LENGTH 1500mm2. ELECTRIC POWER 20KW3. TEMPERATURE 850C
BURNOUT SECTION1. LENGTH 2000mm2. ELECTRIC POWER 20KW3. TEMPERATURE 1350C

where P(n) is the power density of the nth frequencycomponent f(n) of the flame signal, and N is the total
numberof frequency components
The following matrixes would be inducted.

Correlation coefficientof two matrixes X(n) and Y(n) can be calculated as following

CONCLUSION
A FLAME MONITOR INCLUDING FLAME DETECTOR IS USED TO IDENTIFY
COALS IN A DROP TUBE FURNACE.BY EXTRACTING AVG,STDDEV,OSC FREQUENCY MATRIX OF FLAME SIGNAL.CALCULATE CORRELATION
COEFFICIENT OF THE MATRIXES BOTH SINGLE &BLENDED COALS CAN BE
IDENTIFIED FAST ONLINE
