Biomass Thermal Oil Boiler Project for a Large Wood Processing Enterprise in Paraná State, Brazil

Project Overview

The state of Paraná in Brazil is a major timber processing hub in South America. A large local timber processing enterprise requires a stable, high-temperature heat source during its production process for wood drying and plywood hot pressing. As production capacity increased, the existing coal-fired thermal oil boiler revealed issues such as high energy consumption, significant pollution, and unstable heat supply, which not only increased production costs but also created pressure from increasingly stringent environmental regulations.

To reduce energy costs and achieve green production, the company partnered with Huanuo Boilers to introduce a biomass thermal oil boiler system, fully utilizing the region’s abundant wood processing by-products to establish a circular economy production model.

Customized Heat Source Design

The boilers feature a horizontal coil structure with ample heat transfer surface area, enabling rapid heating of the thermal oil and precise temperature control—fully meeting the strict requirements for a stable, high-temperature heat source in wood drying and plywood hot pressing.

Turning Waste into Treasure, Significantly Reducing Fuel Costs

By fully utilizing abundant local biomass resources—such as wood scraps, bark, and wood chips—as fuel, the system not only resolves solid waste disposal challenges but also significantly reduces fuel procurement costs, achieving resource recycling.

Ultra-Low Emissions, Green and Compliant

Equipped with multi-stage dust removal and flue gas purification systems, the flue gas emission concentration is 30% lower than local emission standards, successfully passing environmental protection inspections.

Intelligent Control, Stable Operation

The boiler employs a fully automated control system that automatically adjusts combustion intensity based on process load, ensuring stable and reliable heat supply and eliminating the issue of temperature fluctuations—which previously affected product quality in the original coal-fired boiler.

Core Project Advantages

Fuel costs have decreased significantly compared to the original coal-fired boiler, with annual fuel cost savings of approximately 30% and a short payback period.

Biomass fuel is sourced locally, resolving the challenge of disposing of large amounts of wood waste and reducing solid waste disposal expenses.

Emission indicators exceed local environmental standards, enabling the company to successfully obtain “Green Factory” certification and enhance its market competitiveness.

Stable heat supply and precise temperature control have significantly improved the yield rates for product drying and hot pressing.

Client Testimonial

“Huanuo Boiler’s biomass thermal oil boiler perfectly meets our production needs. Not only has it solved the problem of waste wood disposal, but it has also drastically reduced heating costs—truly turning waste into treasure! This has been a genuine win-win collaboration.”

“Food processing has strict requirements for both steam quality and emissions. Huanuo’s condensing steam boiler has high thermal efficiency and a low exhaust gas temperature, with NOx emissions far below local standards. It helped us easily pass environmental reviews, while natural gas costs have also dropped noticeably.”

Khalid Al-Farsi

Plant Manager, a food processing plant in Saudi Arabia

“We use local agricultural and forestry residues as boiler fuel. Huanuo’s biomass steam boiler has strong fuel adaptability and runs stably, which not only reduces fuel costs but also eases solid waste disposal pressure. Emission indicators meet local environmental requirements, and the overall benefits have exceeded expectations.”

Johan van der Merwe

Energy Manager, a beverage producer in South Africa

“Chemical plants have extremely high requirements for heat source continuity. The waste heat boiler customized by Huanuo fully recovers waste heat from process tail gas and produces steam stably, significantly reducing the cost of purchased steam. Since commissioning, the equipment has operated reliably and provided real help for our energy-saving and consumption-reduction efforts.”

Rajesh Kumar

Technical Director, a chemical company in India

“Our region has long winters and extremely low temperatures, so heating equipment must withstand severe conditions. Huanuo’s hot water boiler starts quickly and supplies heat stably even in low-temperature environments. Throughout the entire heating season, there were no unplanned shutdowns, and our residential heating guarantee capability has improved markedly.”
