Gas Cremation Furnace: A Smarter, Cleaner, and More Sustainable Alternative

For crematoriums, municipalities, hospitals, and service providers, modernizing the cremation process is no longer a matter of choice—it’s a necessity. Between stricter environmental guidelines, rising fuel costs, space limitations, and increasing cremation volumes, traditional wood-based systems are proving inefficient and unsustainable. This is where a gas cremation furnace provides a practical, high-performance solution. It offers clean combustion, faster cycle times, and minimal manual intervention, all while significantly lowering environmental impact. At Science Udyog, we’ve worked extensively with clients across India to install and maintain reliable gas-fired cremation furnaces designed to meet real-world demands. Whether you’re upgrading from an open-pyre setup or planning a new facility, this guide will walk you through everything you need to know—from how it works to pricing, installation, and long-term benefits.

Mortuary Chamber

A gas cremation furnace uses LPG or PNG as fuel instead of traditional wood or coal. The system consists of a refractory-lined primary chamber, one or more high-efficiency gas burners, temperature sensors, and a controlled exhaust outlet. When the body is placed into the chamber, the burners ignite and heat the chamber to around 850–950°C. At this temperature, combustion is complete, meaning there’s minimal visible smoke, no foul odor, and far fewer particulate emissions. The entire process takes around 60 to 90 minutes, depending on the system and body weight. Unlike open pyres, gas-based systems are closed, cleaner, and require almost no manual handling once the cremation starts. What truly sets them apart is consistency. Regardless of weather or wood quality, the gas flame delivers a uniform burn every time. This not only ensures dignity in the process but also makes operations smoother for the facility.

The shift toward gas-fired cremation furnaces is happening across India—not just in metro cities but increasingly in Tier 2 and 3 regions. One major reason is air quality compliance. With pollution boards enforcing stricter emissions standards, traditional open cremation is coming under scrutiny. Wood cremation releases a significant amount of smoke, carbon monoxide, and even methane. In contrast, a well-designed gas cremator reduces emissions by over 80%. Second, operational efficiency is a strong motivator. In high-volume settings, managing multiple cremations with wood can be chaotic and labor-intensive. Gas systems are cleaner, quicker, and easier to control. Finally, public perception is evolving. Many families now prefer cleaner, modern systems—especially in urban areas where health awareness is higher. For crematorium operators, adopting gas-based systems is about future-proofing their services while reducing operating stress.

Let’s address a question that comes up early in every discussion: what does a gas cremation furnace cost? The answer depends on several factors—capacity, automation level, type of gas, materials, and whether you’re installing a single or multi-chamber system. At Science Udyog, we offer models that range from compact single-body units to high-capacity multi-chamber systems. On average, here’s what you can expect:

Single-Body Unit: ₹8,00,000 – ₹12,00,000
Multi-Chamber Furnace: ₹15,00,000 – ₹25,00,000
Installation & Civil Work: ₹1,00,000 – ₹3,00,000
Annual Maintenance: ₹10,000 – ₹25,000

While this may seem like a steep investment initially, it’s important to look at operational savings over time. You save significantly on fuel, reduce dependency on labor, and avoid penalties related to non-compliance with pollution norms. In many cases, facilities recover their investment within 3 to 5 years through improved efficiency alone.

At Science Udyog, we’ve worked with crematoriums of all sizes—from small municipal setups to large private facilities. Our designs focus on real-world use. Each gas cremation furnace we build comes with key performance features, including:

Stainless Steel or MS Outer Body for durability
Fully Refractory-Lined Inner Chamber for thermal efficiency
High-Quality Italian/Indian Gas Burners
Automated PLC-Based Temperature Controls
Eco-Chimney & Pollution Control System
Custom Layout Support & Civil Work Assistance

Our strength isn’t just in manufacturing but in offering end-to-end support—including site assessment, technical drawings for approvals, installation, operator training, and maintenance. When you work with us, you’re not buying a product; you’re getting a long-term operational partner.

Who Should Consider Installing One?

If you’re running or planning to build a cremation facility, a dead body cremation furnace powered by gas is a smart, future-ready choice. Here’s who benefits most:

Municipal Crematoriums: Serve high volumes while meeting green norms
Hospitals: Quick, hygienic, in-house cremation of unclaimed bodies
Private Cremation Service Providers: Offer clean, premium services to families
Charitable Trusts and NGOs: Eco-friendly, community-focused solutions
Religious Institutions: Maintain tradition while embracing technology

We also work with urban planning departments and contractors who need assistance integrating such systems into smart city projects or upgraded cremation grounds.

Installation, Layout & Compliance Made Easy

Installation is often a big worry for first-time buyers. “Will my space fit the furnace?” “What about civil works?” “Will I need multiple permits?” At Science Udyog, we make this part of the process seamless. We offer customizable layout drawings, help you plan chimney routing, and guide you through foundation and exhaust setup. We also assist with CPCB/NGT documentation, helping you stay compliant from day one. Our team trains your operators on safety, start-up procedures, emergency protocols, and shutdown operations. The goal is to ensure you’re not only compliant but confident in your system’s day-to-day use.
