Turn key SCR deNOx system for gas turbine boiler at DONG Energy Horsens CHP (combined heat and power) plant A/S
The main data of the existing plant are as follows:
1. Flue gas amount: 71,5 kg/s;
2. Gas turbine, model GE LM250PE;
3. Degasification type: Aalborg Ciserv A/S LV24;
4. Current NOx level, both with and without water injection:
a) Without water injection: 1 100 mg/Nm3;
b) With water injection: 680 mg/Nm3.
The new SCR (selective catalytic reduction) plant must comply with the following requirements:
5. The following emissions must as a minimum be observed after installation and commissioning. When determining the level of NOx emission, all NOx must be converted into NO2. In practise, the emission of NO and NOx is measured in ppm. The found values must be added up and the sum must be converted into mg/normal m3 NO2 by the use of the conversion factor for NO2.
— The NOx emission must be kept under 150mg/Nm3 (reference state: 5 % 02, 0 degrees Celsius, 101.3 kPa, dry gas under all operational conditions,
— The ammonia emission must be kept under 12mg/Nm3 (reference state: 5 % 02, 0 degrees Celsius, 101.3 kPa, dry gas under all operational conditions.
The following is included in the supply:
— The existing ammonia storage must be used (24 % dissolution, (NH3) in connection with the installation of the plant,
— Pipe routing, pumps and electrical installation as regards connection to existing ammonia storage,
— Assembly and installation in the time frame (May 2012, June 2012, July 2012),
— Commissioning in the time frame (August 2012). Must be able to comply with emission requirements as of 1.9.2012,
— Scaffolding, insulation in connection with assembly and installation,
— Commissioning,
— Documentation Electronic + 2 x hard copy,
— Operational description (maintenance manuals) electronic + 2 x hard copy,
— C&I concept for control system (Siemens T-3000),
— Third party control and verification of emissions in connection with commissioning,
— KKS numbering of drawings, components, pipe routing and cables.
