Steam Generation Systems
At the request of our clients, we integrate environmental control systems (combustion gases) into our projects; water treatment; unloading, transport, and dosing of solid fuels (coal, biomass); adaptation and transport of ash (derived from combustion gases); economizers; desuperheaters, and purge heat recovery systems.
We guarantee compliance with Resolution 909 of the Ministry of the Environment, Housing, and Territorial Development, for polluting atmospheric emissions, with filterbags, multi-cyclones, desulfurizers, burners, and state-of-the-art instrumentation and control systems.
We ensure the safety of the process, implementing maintenance and combustion calibration routines and updating the instrumentation and control, in compliance with the NFPA 85 standard and the ASME code, VIII.
We supply SCADA-type supervision and management systems for the management of indicators, traceability of the operation, historical record and data storage for environmental authorities, historical record and storage of alarms for detection and diagnosis of failures, hour meters integrated into maintenance plans.
In each of the disciplines (mechanical, process, electrical, automation, and projects) we have the ideal human capital for each stage in which our client requires it: cost evaluation, design, manufacturing, testing, assembly, commissioning, training, and maintenance.
We add proven automation and supervision methodologies to reduce fuel consumption and optimize efficiency and performance in the operation of our steam generation systems, through:
- Air-fuel ratio control with oxygen feedback in combustion gases.
- Control of the air-fuel ratio with feedback of CE [FM6] in combustion gases.
- Water level control with one, two, or three measuring points.
- Closed loop fuel injection control with flow feedback.
- Surface purge control with conductivity measurement inside the boiler.
- Bottom purge control by timing.
- Water exchange flow control for efficient energy use in boiler purge.
- Control of water and gas flow in economizers for their performance and protection against acid condensation.
Use of speed variation for energy-saving and fine control, in combustion air injection fans, induced draft fans, and water feed pumps.
