Heavy Fuel Oil Additives for Power Generation

Thermal power stations firing heavy fuel oil face a chemistry problem in the furnace itself: vanadium and sodium in the fuel form low-melting ash that fouls superheaters, while sulphur products attack the cold end. CHIMI MAG 30 and CHIMI MAG 20, organo-magnesium additives at 30% and 20% active content, are injected continuously into the fuel line to address this. Magnesium chemistry typically converts vanadium compounds into higher-melting ash that normal sootblowing can remove, supporting combustion enhancement and emissions reduction — plant trials on your own fuel remain the deciding evidence. For a base-load HFO unit with high fuel throughput, CHIMI MAG 30 concentrates more active magnesium per litre of additive handled; CHIMI MAG 20 gives finer dose adjustment for smaller boilers, peaking units, or diesel-engine plants. A power-plant buyer should start from the fuel certificate values — vanadium, sodium, and sulphur per delivery — and ask the supplier to propose a dose rate tied to those numbers, an injection and mixing arrangement, and a measurable trial protocol: deposit condition at inspection, sootblowing frequency, and back-end temperatures. Clarify storage logistics (drums or IBCs, 18-month shelf life), dosing-skid materials, and how dosing will track fuel-quality changes between shipments.
