Control
A boiler control system has to hold steam pressure and temperature steady while fuel demand, feedwater, and air flow all move at once, and it has to do it safely, because the same equipment stores enough energy to be dangerous when mismanaged. Drum level, combustion air-fuel ratio, furnace draft, and steam-temperature control interact continuously across load, and the control strategy must keep them coordinated through startup, load swings, and trips.
We engineer the Boiler Control System from the algorithm level up, matched to each unit’s firing, heat-transfer, and feedwater configuration, and develop it to IEC 61131-3 so proven control strategies deploy on the platform that best fits your lifecycle, with full logic access and no license walls.
The Problem
Capabilities
We supply a Burner Management System engineered independently of the modulating controls and aligned to NFPA guidance for fuel-fired equipment. The BMS enforces permissives, supervises flame, executes safe shutdown on any unsafe condition, and is implemented on a safety-rated platform whose safety integrity level is set by the customer's HAZOP. Exact SIL targets are project-specific.
Coordinated fuel and air control holds the air-fuel ratio through load changes with cross-limiting so air leads on increasing load and fuel leads on decreasing load, protecting against fuel-rich excursions. Furnace-draft and, where applicable, oxygen-trim control are integrated to maintain efficient, stable combustion across the operating range.
Each burner's flame is supervised by dedicated flame scanners with discrimination logic to confirm the correct flame is present and to detect loss of flame. Loss-of-flame conditions trip fuel to that burner or the unit per the safety design, and scanner health and flame-signal strength are continuously monitored and trended.
For fired and unfired HRSGs we manage duct-burner firing where present, feedwater and drum level across pressure levels, and steam-temperature control via attemperation. Startup and load-following sequences are coordinated with the gas turbine or heat source, with hold points and full alarm and diagnostic messaging.
Before any light-off, the BMS enforces a timed furnace purge at proven airflow to clear combustibles, then steps through igniter proving, main-fuel valve permissives, and flame confirmation in the NFPA-aligned sequence. Every permissive, timer, and interlock is testable, and the full sequence is exercised and documented during Factory Acceptance Testing.
Real-time diagnostics track flame quality, valve and damper position, combustion performance, and BMS trip first-out, exposing alarms, sequence-of-events, and trends to plant historians and asset-management systems. First-out annunciation makes the cause of any trip immediately clear to operators for fast, safe recovery.
We implement single-, two-, and three-element drum level control with shrink-and-swell compensation, feedwater-valve and pump coordination, and independent high/low drum-level trips. The strategy is tuned to the unit's drum geometry and load-change rates to keep level stable through swings while protecting against carryover and low-water conditions.
Why Innova Technologies
We deliver the Burner Management System independent of the modulating controls, aligned to NFPA guidance, on a safety-rated platform whose safety integrity level is set by the customer’s HAZOP, so a control fault is designed not to defeat the safety function.
Technical Resources
The safety integrity level is set by the customer’s HAZOP and safety-requirements specification, not chosen by us in isolation. We implement the BMS on a safety-rated platform sized to meet the assigned SIL, then verify it through SIL calculations and document the results during design review and FAT.
Safety kept separate from control, so a single fault cannot compromise both.
We supply a Burner Management System engineered independently of the modulating Boiler Control System and aligned to NFPA guidance for fuel-fired equipment. The BMS supervises flame with dedicated scanners, enforces a timed furnace purge and the full light-off permissive sequence, and executes safe shutdown on any unsafe condition. It runs on a safety-rated platform whose safety integrity level is set by the customer’s HAZOP, so a control-system fault is designed not to defeat flame supervision, purge enforcement, or the trip function.
Independent control for every turbine class.
Anti-surge, loadshare, performance, and capacity control.

A MESSAGE FROM JOHN KAZOUR, CEO
To our customers and partners,
For more than 50 years, our team has helped customers keep critical operations running. We built our reputation as Petrotech by taking responsibility for control systems on important rotating machinery.
As more industries came to us with similar challenges across power generation, compression, and hydro applications, our engineering team kept finding ways to solve them. Eventually, the business outgrew the Petrotech name.
We are entering our next chapter as Innova Technologies. The new name reflects the full scope of our work as a rotating machinery control systems specialist. We engineer controls around the machine, deliver complete projects from design through commissioning, and provide support that stays with the problem until it is solved.
Our name is changing, but the people, engineering experience, and commitment behind the work continue. Our responsibility to active projects and installed systems carries forward under the Innova Technologies name. Your current contacts remain the right place to start, and we will communicate directly if an administrative record requires an update.
We appreciate the trust you have placed in us over the decades, and we look forward to continuing that work as Innova Technologies.
CEO, Innova Technologies
