ALZETA Corporation, world leader in Ultra-Low NOx burner technologies, delivers the “system solution” for atmospheric boiler operators requiring compliance with BAAQMD Regulation 9, Rule 7. 

The advantages of ALZETA's proven burner system include:

  • Modular system design, simple operation, quick and easy installation
  • Less than 15 ppm NOx @ 3% O2
  • Low pressure drop, anti-plugging surface
  • Capacities from 1 million to 10 million Btu/hr
  • Durable cast-iron body and steel manifold fit within the boiler
  • Complete system with combustion air blower, gas train, boiler and burner controls and instrumentation
  • Applicable to all atmospheric systems: RITE,AJAX, PARKER, and many others

ALZETA developed our first atmospheric boiler retrofit package in the 1990’s for the Southern California market. The new FireStar™ is the system for 2011 and beyond. This package takes advantage of the latest in pre-packaged boiler controls; replacing and modernizing the existing the boiler and combustion control system. Your boiler will continue to provide reliable service for many years to come.

Based on our SB 505 burner module, capacity is added in ½ million Btu/hr increments—increasing capacity simply means adding another module. ALZETA applies its design expertise to select a burner array to match the internal layout of the boiler. You never need to worry about localized hot spots, bypassing, or non-uniform performance.

Systems arrive ready to install including:

  • Pre-assembled gas train
  • Control Panel and water level sensors
  • Partially assembled manifold (to permit easy transport up to the boiler site)
  • Combustion air blower, filter, fuel-air mixing assembly

Installation typically takes one or two days after removal of the existing burner system. Many Bay Area atmospheric boilers are roof-mounted, so having modular system components that can be hand-carried to the point of installation is an installer’s delight!

ALZETA maintains a fully functional boiler at our facility to demonstrate our FireStar™ burner system and to provide training for installers and operators.
