- For instance, Kenuo Boiler’s PGS Series condensing steam boilers for chemical use may report a heat-efficiency rating of 102% (based on the fuel’s Lower Heating Value, or LHV), while maintaining ultra-low NOₓ emissions of ≤ 30 mg/m³. This efficiency figure is a common industry measurement, but the actual maximum thermal efficiency relative to the total energy available in the fuel (Higher Heating Value) is typically around 90-98.5%.
Expansion of Specialty Chemicals and Petrochemical Facilities
The specialty chemicals sector grows rapidly due to strong demand from pharmaceuticals, agrochemicals, electronics chemicals, and performance materials. These facilities require high-pressure, consistent steam supply, which strengthens the need for advanced water tube boilers. Many petrochemical complexes also expand cracking, reforming, and extraction capacities, leading to higher thermal-energy needs. Growing investments in polymer, resin, and chemical intermediates production encourage adoption of boilers that support stable output and high temperature control. New capacity additions across Asia-Pacific and the Middle East further boost demand for gas fired water tube boilers, as regional governments support large-scale chemical manufacturing zones and integrated industrial clusters.
- For instance, Thermax secured an order for 3 oil- & gas-fired water-tube boilers for a refinery and petrochemical complex in western India, underscoring the rising steam demand in expanding petrochemical hubs.
Shift Toward Cleaner and Low-Emission Fuel Choices
Chemical producers face strong pressure to meet environmental compliance requirements and reduce carbon output. Gas fired water tube boilers support this shift by offering clean combustion, lower particulate release, and reduced sulphur and nitrogen emissions compared to oil or coal-based units. As countries introduce tighter emission caps, plants accelerate the transition to natural-gas-based systems. Many facilities also incorporate low-NOx and ultra-low-NOx burners to meet regional air-quality norms. Rising carbon-pricing policies and corporate sustainability commitments drive long-term investments in gas-based boilers, making them preferred choices for modernization programs and greenfield chemical projects.
Key Trend & Opportunity
Growth of Condensing Technology in Chemical Processing
Condensing boilers gain strong traction due to their ability to capture latent heat from exhaust gases, delivering higher fuel utilization and meaningful reductions in operating costs. Chemical plants increasingly replace non-condensing systems to enhance thermal performance and comply with emission standards. The opportunity expands as producers integrate flue-gas recovery systems and digital monitoring tools that optimize combustion in real time. Rising need for energy savings in high-steam-demand units supports wider use of condensing models, particularly in regions implementing aggressive decarbonization targets. This shift creates new opportunities for suppliers offering high-efficiency, corrosion-resistant heat-exchanger designs suitable for chemical steam operations.
- For instance, Viessmann offers a Vitotrans 300 flue gas/water heat exchanger (economizer) as an accessory for their Vitomax and Vitoplex industrial/commercial boilers.
Adoption of Automation and Smart Boiler Control Systems
Advanced automation tools improve safety, reliability, and fuel-to-steam conversion rates. Chemical manufacturers adopt smart controls to manage variable steam loads, adjust burner output, and monitor operational health. IoT-enabled sensors track temperature, pressure, and flue composition, enabling predictive maintenance and reducing downtime risks. This creates strong opportunities for vendors offering intelligent boiler management systems compatible with distributed control systems (DCS) used in chemical plants. Digital platforms also support remote performance monitoring and better compliance tracking. As plants move toward Industry 4.0 integration, demand for automated, data-driven boiler systems grows significantly across both new and retrofit installations.
- For instance, Miura equips its boilers with a BL Micro Controller, which continuously monitors key parameters like steam pressure, water level, feedwater temperature, and exhaust temperature and can detect faults, pinpoint their source, and recommend corrective actions in real time.
Rising Preference for Modular and Skid-Mounted Boiler Systems
Chemical facilities increasingly prefer modular, skid-mounted water tube boilers because they reduce installation time, simplify layout integration, and support rapid scaling of steam capacity. Modular designs also enhance flexibility during plant expansion or process reconfiguration. The trend gains momentum as chemical producers deploy temporary or supplemental boilers during maintenance shutdowns or seasonal demand spikes. Suppliers offering compact, high-output modular systems gain an advantage in markets requiring fast deployment. This shift presents significant opportunities for boiler manufacturers to supply customizable, high-efficiency modules that meet strict safety and emission standards in diverse chemical processing environments.
Key Challenge
Compliance with Stringent Emission Regulations
