NH3 injection lowers NOx in stack flue gas, boosts dust collection efficiency, and prevents erosion. Precise measurement and control of NH3 are crucial to avoid excess use, which increases costs and causes odors. The TDLS8000 solves these issues with direct measurement for effective NH3 management.
Introduction
In a boiler application, ammonia (NH3) gas is injected to remove nitrogen oxides (NOx) and reduce the NOx concentration in the stack flue gas. Conventional analyzers obtain the NH3 concentrations indirectly through a sampling system. The sampling system introduces time delays in the measurement and increases maintenance costs. Since the TDLS8000 Laser Analyzer does not use a sampling system, it solves such problems. The TDLS8000 Laser Analyzer solves these issues with direct measurement, eliminating sampling needs and offering real-time data, necessary accuracy, and efficiency for effective NH3 management.
Continuous Monitoring: Ensures constant NH3 emission sampling system,
it is a solution to track environmental compliance.
Process Overview
The NH3 gas is injected to reduce the NOx concentration in the stack flue gas, increase the dust collection efficiency of the dust collector (ESP), and prevent erosion. Excess NH3 injection increases the running cost and the amount of residual NH3, which results in a foul odor. Therefore, it is essential for boiler operators to closely monitor and control the NH3 concentration in the stack flue gas.

Cost Reduction: No sampling system is needed, cutting maintenance and operational costs.
Solution
Compared to conventional NH3 analyzers, which perform measurements through a sampling system, the TDLS8000 can measure the NH3 concentrations in furnaces directly and, thus, reduce maintenance and running costs. The TDLS8000 is entirely field repairable; there is no need to return the analyzer to the factory for service or repair.
Enhanced Equipment Life: Real-time measurements extend NOx removal,
equipment lifespan, and reduce ammonium sulfate buildup.
Field Data
Since the TDLS8000 rapidly responds to NH3 concentration changes, it can provide timely process variable updates for optimum injection control.

Chemical
Chemical plants rely on continuous and batch production processes, each posing different requirements for a control system. A continuous process calls for a robust and stable control system that will not fail and cause the shutdown of a production line, whereas the emphasis with a batch process is on having a control system that allows great flexibility in making adjustments to formulas, procedures, and the like. Both kinds of systems need to be managed in available quality history of product, and to be able to execute non-routine operations. With its extensive product portfolio, experienced systems engineers, and global sales and service network, Yokogawa has a solution for every plant process.
