As seen in POWER Magazine Inconsistent fuel quality puts constant strain on aging waste-to-energy boiler systems. Modernizing startup burners, combustion controls, and flame detection can restore reliability and keep plants code-compliant—without the cost of a full replacement. Waste-to-energy (WTE) infrastructure turns municipal garbage into usable power. In theory, the process is efficient, reliable, and sustainable. Unfortunately, the reality […]
Growth and Sustainability With Ultra-Low & Nano-NOx Burners
Environmental regulations continue to evolve and tighten around NOx emissions. In parts of Northeast and Southern California, sub-9 ppm NOx combustion for natural gas has already become the practical standard, while states like Maryland have proposed phased adoption of near-zero-NOx systems for institutional boilers by 2029. A facility’s emissions profile now directly influences whether it can renew operating […]
