Mobile SNCR & Temperature Measurements Services
It is advisable to carry out tests with a test facility in order to obtain further planning security. With the tests, additional information is obtained with reasonable expenditure of time and money on whether the required NOx and NH3 limit values can be safely met, even with changing boiler loads, and what technical effort may be required.
- SNCR operational tests & feasibility studies with urea solution (40/45 % by weight) or ammonia water (25 % by weight) as reducing agent
- Suitable for automated multi-level operation for injection with different boiler loads
- Individually switchable injection lances
- Integration of NOx setpoints possible
- Commissioning of the plant
- Support or implementation and evaluation of the operational tests
- Provision of injection lances, flexible hose connections, pump modules, etc.
- Provision of reducing agents
- Control cabinet with S7 control
- Remote maintenance unit
- Deionized / process water water pressure increase pump
The test setup consists of a urea tank (here: tank truck with 25 m³ volume), a feed pump module for urea solution / ammonia water, a test module for dosing and regulating the quantities, connecting rubber hoses, connection flanges on the boiler and injection lances.
Urea solution / ammonia water is pumped from the tank truck to the test module by means of the feed pumps via a rubber hose. In the test module, the required amounts of urea solution / ammonia water, water and compressed air are set and conveyed to the injection lances via hoses. The nozzles in the lances are used to inject into the boiler.
