Advantages

Our recovery boilers optimize the efficiency of the entire system and help combat environmental challenges by reducing NOx and CO2 emissions.

These solutions are made to order and fully customized. Recovery processes are designed after analyzing the sources of excess heat and the process needs. This approach maximizes thermal efficiency and increases plant reliability.

The OptiSpark automatic control system provides rapid response to changes in operating parameters and optimizes the steam generation process under increasing or decreasing load conditions.

The design is conceived to simplify maintenance operations, with easy and full accessibility to all system parts. To clean the furnace and smoke pipes from ash and slag, waste heat boilers can be equipped with automatic soot blowers.

Reduced operating costs.

Technology

Smoke tube solution

The HRSG heat recovery units are based on the proven fire tube technology of the SM/SG conventional steam boilers. The boilers also have a reversible firebox, completely shielded by a grate of fire tubes. For ease of operation and maintenance, there is direct access to the inversion chamber and a complete view of the pipes, the tube plate and the firebox.
The boiler drum and fire tubes are made of strong steel and connected by arc welding. This solution is designed for ICE – Internal Combustion Engines – to optimize the heat recovered on the exhaust and reduce the generated backpressure. An extra recovery system can be added to improve recovery performance.

Oil heater design

HTHR oil heat recovery units are based on the proven HTH multitubular boiler technology for conventional fuels and biomass, with a large combustion chamber followed by the convective section. Its low thermal load means a longer operating life of the thermal oil.

Construction of CTR waste heat boilers

The CTR heat recovery units are based on the patented multitubular design of the CT boilers, operating on natural gas and traditional oil fuels. These boilers are designed for industries where high pressure and flexibility in load control are required, in addition to high power. Enterprises using this equipment include large chemical and pharmaceutical companies, oil refineries, and thermal power plants.
Superheated water heat exchangers have a D-shaped design with two drums located in the upper and lower parts of the body. At the junctions with the drum, the pipes are expanded using automatic equipment. The water inside the boiler circulates naturally, and the required gas tightness is achieved from the outer walls with membrane panels.
