Coal Nozzle Top Plate Manufacturer In Vapi

Precision-Cut Plates for Thermal Efficiency

We are supplying coal nozzle top plates manufactured to maintain flame stability and direct coal-air mixture into the furnace with controlled velocity. These plates are critical for maintaining combustion quality in coal-fired boilers by ensuring accurate alignment and wear resistance at the nozzle outlet. Built from high-temperature steel or alloy castings, the plates resist slag accumulation, thermal fatigue, and abrasive erosion. Each top plate is machined with tight tolerances to provide precise sealing with nozzle cones, ensuring that the combustion airflow remains undisturbed under load variations and extended operational cycles.

Utility Boiler Systems in Thermal Plants: Widely used in power generation units, these plates help maintain uniform fuel spray and flame coverage inside furnace walls. The top plate’s flat alignment prevents secondary air leakage and unburnt carbon losses, enhancing boiler efficiency.

Captive Power Units in Steel & Cement Plants: Deployed in in-house boiler systems, these plates are part of coal nozzle assemblies that withstand direct exposure to high-temperature coal-air jets. Their consistent performance directly impacts clinker formation, ash fusion, and fuel economy.

Retrofitting and Maintenance in Legacy Boilers: Required during overhauls and boiler upgrades, top plates are installed to replace worn-out or distorted assemblies, restoring original nozzle alignment and performance. They are supplied in custom shapes to suit burner modifications.

Machining Scope

Coal nozzle top plates are manufactured from stainless steel, Ni-hard, or high-chromium castings based on furnace type and fuel ash content. The plates are precision-ground or CNC-milled to match mating surfaces. Anti-slag coatings, ribbed designs, and expansion grooves are incorporated to handle thermal cycling and reduce scale formation. The geometry supports optimal fuel-air dispersion, avoiding hotspots and ensuring uniform combustion. Surface hardness and metallurgical structure are controlled to resist erosion caused by abrasive coal dust and flue gases.

FEATURES

• Built from heat-resistant alloy or SS304
• Flat-milled for perfect sealing with the nozzle cone
• Optional anti-wear coating or ceramic bonding
• Taper-fit or slot-hole designs available
• Custom-cut dimensions as per boiler specification

Orders & Maintenance Support

We, as a company, provide coal nozzle top plates tailored for thermal plants, industrial boilers, and furnace assemblies. In addition to our commitment to quality and customer satisfaction, we offer inspection-ready dispatches, third-party testing (if needed), and reverse-engineered replacements for obsolete plate designs. With precise fitment, wear-resistant metallurgy, and thermal-grade surface finish, our plates support long-term combustion reliability across various fuel grades.
