Boiler package includes a 250 to 800 hp high-pressure, steam firetube boiler that burns either natural gas or No. 2 oil; an integral burner; two-stage condensing economizer that helps maximize heat recovery; level control; and a Hawk ICS control system with parallel positioning. The all-in-one package ensures the boiler technologies are exactly matched, resulting in reduced energy usage. Other technology found in the package includes a deaerator; a combustion air fan with variable-speed drive; and an oxygen trim system in the exhaust gas. The sensor continuously senses oxygen content and provides a signal to the controller, trimming the air damper or gas valve, maintaining a consistent oxygen concentration and minimizing excess air while optimizing the air-to-fuel ratio.
