QUICK ANSWER
A portable flare is a trailer-mounted combustion unit engineered for temporary or mobile flaring — no foundation, no civil work required. Hero portable flares deliver 98%+ Destruction and Removal Efficiency (DRE) to meet EPA 40 CFR Part 60 Subpart OOOO and OOOO-a standards, with stack heights from 13 to 60 feet. Units deploy in 24 to 48 hours and are available to rent or purchase, with in-stock configurations ready for fast mobilization.
What Is a Portable Flare and How Does It Work?
A portable flare, also called a trailer-mounted or mobile flare, is a self-contained flare stack built on a trailer so it can be hauled to a site, set up, and burning waste gas in a short window, then moved to the next job.
It works like a permanent flare: gas is routed up the stack to a tip where a continuously burning pilot ignites it for safe, clean combustion. The difference is mobility. Because the stack, pilot, ignition, flame arrestors, and controls all travel together on one trailer, a portable flare needs no foundation and no permanent install, which is what makes it the practical choice for temporary, remote, or emergency work.
Tell us your site and gas data and we will confirm the right mobile flare.
Applications and Use Cases
Portable flares earn their keep anywhere you need to burn gas safely without a permanent stack. Common uses include:
Drilling and Well Testing
Flowback, completions, and flaring during well testing and production operations where temporary combustion is required.
Pipeline Maintenance
Blowdowns, tie-ins, and pigging operations that require safe combustion of released gas at a temporary site.
Plant Turnarounds
Shutdowns, commissioning, and short-duration plant operations where a portable flare provides rapid, compliant relief.
Tank Battery Vapor Control
Temporary vapor control and combustion during tank battery operations in remote or short-term field settings.
Emergency and Upset Venting
Rapid response when process conditions direct excess gas to a flare and no permanent unit is on site.
Remote and Short-Duration Sites
Locations where a permanent flare is not feasible, cost-effective, or justified for the project duration.
Rent or Buy: Portable Flares In Stock and Ready to Deploy
Most portable flare work is time-sensitive, so Hero keeps trailer-mounted units in stock for fast turnaround. You can rent a portable flare for a short job like a turnaround or well test, or buy one outright for recurring field work.
Because each unit ships complete on its trailer with no foundation required, mobilization is quick: we prepare the unit, ship it, and support installation and commissioning at your site. If an outage or upset could send gas to a flare on short notice, ask us about a rental contingency plan so a unit is lined up before you need it.
See our rentals page or send your timeline and we will confirm current stock.
What’s Included in a Hero Portable Flare
Every Hero portable flare ships as a complete package on a rugged trailer, engineered for transport and quick deployment:
Flare Stack
Heights from 13 to 60 feet to match your dispersion, safety, and site space requirements.
Pilot and Ignition System
Reliable field lighting for safe and consistent operation in any conditions.
Flame Arrestors
For safe operation in all field conditions, protecting against flashback and unintended ignition.
Integrated Control Panel
For monitoring and control during operation, keeping the unit running safely and within spec.
Heavy-Duty Trailer
Built to withstand harsh weather and rugged terrain for reliable field deployment.
Smokeless tip options, including sonic tips, are available when your job requires a clean, smokeless flame. Send your flow and gas data and we will configure the unit.
What Makes a High-Quality Portable Flare System
Portable and rental flare systems must achieve the same DRE performance as permanent installations while tolerating repeated transport, installation, and decommissioning cycles. Five quality indicators separate portable flares that maintain compliant performance across deployments from equipment that degrades quickly in field conditions.
Structural Design for Transport
Bolted stack sections with precision-machined flanges and hardened fasteners withstand repeated assembly and disassembly without developing leaks or misalignment across multiple deployments.
Self-Contained Ignition System
Propane-fueled pilots with battery-powered electronic igniters allow startup without a generator, enabling deployment at remote sites with no grid power.
Quick-Connect Gas Inlets
Hammer-union or cam-lock quick-connect inlets reduce rig-up time from hours to minutes and eliminate the most common field leak point at the inlet connection.
Terrain-Ready Skid Base
Adjustable leveling legs and crane-lift rated lifting lugs allow deployment on uneven wellsite terrain and safe crane pick at limited-access locations.
Manufacturer Mobilization Support
Hero’s rental program offers rapid deployment across the Permian Basin, Mid-Continent, Appalachia, and Rockies with direct field service personnel in the deployment region.

Compliance and Destruction Efficiency
A portable flare still has to burn clean and stay legal. Hero portable flares are fully EPA compliant and proven to achieve 98% destruction efficiency, so your temporary or mobile flaring meets the same performance expectations as a permanent unit.
The pilot, ignition, and flame-arrestor package keeps combustion safe and reliable in field conditions. We can provide compliance wording and documentation for your project file. For more on the current rules, see our OOOOb/c overview, then contact us for the records you need.
Portable Flare FAQs
Most Hero portable flare units can be delivered and operational within 24 to 48 hours of order. Our trailer-mounted systems require no concrete foundation or extended site preparation, so setup is fast even in remote or temporary locations.
Our portable flare units are sized for a wide range of applications, from small gas streams to larger continuous flows. Flow capacity depends on the specific model and burner configuration. Contact our team to match a unit to your flow rate and gas composition requirements.
Yes. Hero portable flares are designed to meet EPA combustion efficiency standards, including 98%+ destruction removal efficiency (DRE). Units can be configured with pilot monitoring, auto-ignition, and data logging to support compliance documentation for air permits and regulatory reporting.
If your project is short-term, a one-time event, or you need equipment quickly without capital expenditure, rental is often the right choice. Ownership makes more sense for recurring operations or multi-site use. Hero offers both options, and our team can help you evaluate total cost of ownership versus rental rates for your situation.
Permanent flare systems are fixed infrastructure requiring substantial civil work, permitting, and long lead times. Portable flares are trailer-mounted, self-contained units that can be relocated, redeployed, or demobilized quickly. They provide the same combustion performance as permanent installations without the capital commitment or site constraints.
No. One of the primary advantages of portable flare systems is that they are trailer-mounted and do not require a concrete pad or permanent foundation. They can be positioned on compacted gravel, a level pad, or existing site surfaces, significantly reducing site prep time and eliminating delays associated with permanent foundation work.
