Blast Furnace

An acoustic pyrometer provides a practical and cost-effective solution for on-line continuous gas temperature measurements within hostile blast furnace environments.

Acoustic Pyrometers Features

• Eliminate other temperature measurement device replacement and maintenance.
• Non-Intrusive rugged design: Stainless Steel Waveguides are outside the furnace wall.
• Suitable for all fuels.
• The system’s lower range is 35^o F allows the system to be used for cold or warm start-ups.
• The upper temperature range is 3500^o F, or nearly 2000^o C.
• Linear and Accurate over the entire temperature range.
• Fault Tolerant Processor Control Unit (PCU).
• The 4-20 mA temperature output is of the path; and with two paths the average, and difference are also available. Any or all outputs easily connect to the computer system for control.
• RS-232 and RS-422 for local monitoring and statistics through local PC.
• Telephone modem for remote monitoring.
• An EEPROM stores all instrument settings.
• Automatic recovery after power loss.
• Remote enable/disable input
• All Software operates on Windows 95/98/2000/XP or NT operating systems, and is included with each system.

More about SEI

Realizing equipment failure raises energy costs, increases labor costs; while production and profit margin decrease, our equipment is designed and built to the highest industry standard.

Sound waves can be used to measure the temperature of a gas, including air, using our Boilerwatch^® MMP Systems. Boilerwatch^® MMP Systems can also be used for multiple paths, contour maps, and temperature distribution mapping. The MMP comes with the TMS-2000 software mentioned above.

For measurement of gas temperature in a boiler the distance between the acoustic transmitter and receiver is fixed and easily measured, and the flight time is measured by the acoustic pyrometer. From this information, the average gas temperature across the path is computed.
