Combustion Research Associates

Pilots 

Pilots manufactured by CRA can be intermittent or continuous, heavy duty or small and with or without retraction capabilities. We offer self aspirating as well as forced air supply pilot burners. 

Flame Front Generator

Flame Front Generator is a highly robust, reliable, long lifetime and low maintenance system that offers economic advantages and an easy retrofit. We manufacture both automatic and manual systems that work with the metering and combining of an air and fuel gas combustion mixture in the ignition line. Our systems are available with Self-aspirating (Self-Inspirating) or forced air supply.

Electronic Ignition Systems

Electronic Ignition Systems utilise High Voltage Direct Ignition (HVDI) or High Energy Direct Ignition (HEDI) systems that are highly efficient, reliable and rugged. In HVDI systems, a high voltage spark is utilised to ignite hydrocarbon gases. In HEDI systems, a high energy capacitance discharge is used to ignite the hydrocarbon gases.

Ignition systems are used to initiate firing in Pilots and/or Burners.

• Pre-piped and pre-assembled units using compatible materials as per the project requirements.
• Pilots available are Continuous Duty or Intermittent Pilots.
• Each pilot is designed to provide flame stability and long life under severe operating conditions including compensation for burner and/or furnace back pressure.
• Special alloy steels are used for critical applications and long life.
• For natural, LPG, Biogas or any other hydrocarbon gases.
• Low fuel gas consumption with adjustment valve.
• Fully Automatic and semi-automatic operations.
• Direct or auto igniters.

 CRA OFFERS FOLLOWING IGNITION SYSTEMS

1.      DIRECT IGNITION SYSTEM

 a)     HIGH VOLTAGE DIRECT IGNITION SYSTEM (HVDI) – In this system high voltage spark is generated to ignite hydrocarbon gases/burner.

 b)     HIGH ENERGY DIRECT IGNITION SYSTEM (HEDI) – High Energy capacitance discharge is used to ignite the Hydrocarbon gases/ burner.  The system is designed to meet the requirements of reliable ignition for many industrial application namely flares, boiler, furnaces etc.

2.      FLAME FRONT GENERATOR TYPE

Flame front generator technology is an effective, time proven ignition system which has been widely used in industry. The inherent reliability, rugged construction, & ease of operation have allowed the FFG to remain one of the most popular forms of ignition system.

Flame Front Generator first meter and then combine fuel gas & air, thereby creating a combustible air/gas mixture in the ignition line. This metering & mixing process is accomplished through the use of small valve trains placed on the FFG control panel.

CRA offers fully automated /manual customized FFG Ignition system in two types:

1.  Compressed  Air Flame front generator
2.  Self -Inspirating Flame Front generator.

CRA has the expertise in design & manufacturing of incinerators and pet cremators for a wide variety of safe disposal of waste. It is designed according to the waste type and the quantity of waste generated for disposal in an efficient, safe and hazard free environment. CRA manufactures incinerators for Bio-medical waste, Animals, Municipal waste, Industrial waste etc.

• Open Elevated flare System
• Enclosed flare system/Thermal Oxidizer.
• Mobile flare system
• Compact Flare System
• Mobile flare system

The ubiquitous flare that offers high efficiency, low operating and erection costs, and above all unmatched dependability. We have been manufacturing elevated open flares for a long time, and have numerous functioning flares in a diverse range of industries.

With this expertise, we aim to offer customizability that delivers just the right requirements for every project.

Utility Flare

Utility Flares are the simplest and most economical type of flaring systems that work well in applications that don't require smokeless burning or where smokeless burning is attained without assistance from air, steam or gas.

Our highly engineered Elevated Utility flares are designed to withstand extreme conditions such as strong winds, high temperatures and oxidizing environments. Our Candlestick flares incorporate Purge Reduction Seals in the tip to save costs and stop flashbacks and a special flame retention ring to aid stable combustion parameters.

Steam and Air Assisted Flares

Assisted flares are designed to dispose of heavier hydrocarbon gases that have a greater propensity to smoke.

Air Assisted flares use blowers to introduce combustion air into the gas stream as it exits the flare tip. A low-pressure blower blows combustion air into an additional riser forcing air into the flare tip, where this air intermixes with the process gas providing clean, economical flaring, extra long flare tip life and reducing emissions.

Steam Assisted flares use injected steam and mix air into the waste gas combustion zone to provide turbulence and allow for a completely smokeless operation. The system directs steam into the waste gas using central steam spargers, peripheral rings and inner induction tubes (optional).

Common Applications

• Oil & Gas Fields

• Chemical Plants

• Waste Water Treatment Plants

• Sewage Treatment Plants

• Landfill Sites

• Refineries and Pipelines

• Food processing

• Natural gas compression and production

Additional Information:

• Item Code: OF-008

Ideal for minimizing flaring impact, enclosed ground flares eliminate visible flame and smoke from flaring waste gases. This refractory lined combustion stack also eliminates thermal radiation and minimizes noise. These features make our flare suitable for operation in plants with proximity to crowded areas, processing equipment and environmentally sensitive areas.

Wastes such as natural gas, LPG, biogas, landfill gas, producer gas, syn gas, cbm gas, vapors and other combustible gases can be eliminated with burning at ground level and a smokeless and invisible flame.

Common Applications

• Oil & Gas Fields
• Chemical Plants
• Wastewater Treatment Plants
• Sewage Treatment Plants
• Landfill Sites
• Refineries and Pipelines

Common Wastes

• Volatile Organic Compounds (VOCs)
• Benzene
• Butyl Chloride
• Low BTU Gases
• Chlorinated Hydrocarbons

Thermal Oxidizers act as emission and pollution control devices to curb industrial pollution in the form of dangerous hydrocarbons such as BTEXs, Sulphur & Volatile Organic Compounds (VOCs) and Hazardous Air Pollutants (HAPs).

Our system is capable of achieving very high (over 99%) Hydrocarbon Destruction and Removal Efficiency (DRE). We also offer heat recovery (Optional) Recuperative & Regenerative Thermal Oxidizer (RTO) systems that offer high thermal efficiency, in turn helping achieve low operating costs, energy consumption with fast payback on investments.

Common Applications
