“CEMTEC® guaranties more than fuel saving and pollution reduction in cement kilns”: 

“CEMTEC® guaranties more than fuel saving and pollution reduction in cement kilns” (Case story – Cement plant in Germany) THE GOAL: Achievement of an optimum in combustion and pollution control for cement plants

Are you familiar with these problems?: 

Are you familiar with these problems? ENOTEC have the solution for these problems Blocked Measuring Tubes Bended Measuring Tubes Immobilisation of the Measuring Tube Defective cooling water hoses due to friction Overstraining of the material by perseverative bending Sampling hose to the analyser cabinet 15- 20 m Slow extractive measurement

ENOTEC: 

has been founded in 1980 in Germany has her own R & D, manufacturing and global sales organisation is focusing on non sampling InSitu analysers for combustion optimisation. ENOTEC Who is ENOTEC?

The ENOTEC Product Range and Applications:: 

COMTEC® True InSitu O2/COe-Analysers for all flue gases from any type of fuel, especially for high dust applications, as well as ATEX explosion (gas and dust) approved versions for any hazardous area (COMTEC® 6000 Ex) for the operation e.g. in cement plants, power plants and refineries. CEMTEC® True InSitu O2/COe-Analyser system for high temperature and high dust areas like cement kilns, lime stone kilns, incinerators and power plants. Fast closed loop control of the air/fuel-ratio and protection of the electrical precipitator. The ENOTEC Product Range and Applications: SYSTEC Customised process and emission analysing systems for SO2, NOx …. CH4 OXITEC® True InSitu O2-Analysers from small boilers (OXITEC® ECONOMY) to large boilers (OXITEC® 5000) and special versions for high dust applications as well as ATEX explosion approved versions for hazardous areas (OXITEC® 5000 Ex), for the operation e.g. in cement plants, power plants and refineries.

The Problems are:: 

Blocked Measuring Tubes Bended Measuring Tubes Immobilisation of the Measuring Tube Grinding Hoses Defective Connection Slow extractive Measurement The Problems are:

The solution is CEMTEC®: 

The solution is CEMTEC®

CEMTEC® Solutions in details: 

CEMTEC® Solutions in details Blocked Measuring Tube The CEMTEC® Solution: Mechanical cleaning by pushing every 2 minutes (without disruption of the measurement) Cleaning with compressed air every 60 minutes.

CEMTEC® Solutions in details (2): 

CEMTEC® Solutions in details (2) Permanent turning of the probe The probe is bended by thermal and mechanical load. Bended Measuring Tubes The CEMTEC® Solution:

CEMTEC® Solutions in details (3) : 

CEMTEC® Solutions in details (3) Clinker sticks to the probe, so that the probe cannot be pulled out off the process any more. Immobilisation of the Measuring Tube The CEMTEC® Solution: Permanent turning of the probe prevents that clinker sticks to the probe.

CEMTEC® Solutions in details (4): 

CEMTEC® Solutions in details (4) The probe cables and hoses are damaged by friction, which can lead to a breakdown of the measurement. The hoses are fixed in an E-chain®, so that they cannot be damaged. Defective cooling water hoses The CEMTEC® Solution:

CEMTEC® Solutions in details (5): 

CEMTEC® Solutions in details (5) With the run-in and the retract of the probe the cables are bent again and again at their connections. This leads to an overstraining of the material and the break-down of the measurement. The hoses are fixed, so that they cannot be bent at the connection neither at the run-in nor at the retract of the probe. Defective Sampling hose The CEMTEC® Solution:

CEMTEC® Solutions in details (6): 

CEMTEC® Solutions in details (6) The measurement is very slow, because all values are measured by an extractive analysing system 15 or 20 m away. The most important values are measured very fast by the InSitu probe COMTEC® 6000 Slow extractive Measurement The CEMTEC® Solution: Sampling hose to the analyser cabinet 15 - 20 m

Measured O2 Values detected at Funnel Tube/Rotary Kiln by Comparison: 

Measured O2 Values detected at Funnel Tube/Rotary Kiln by Comparison Green = CEMTEC (InSitu) / Orange = extractive

Results : 

Results After three years of operation: less energy consumption less pollution less maintenance less analyser downtime increased refractory lifetime
