South San Francisco, CA
BACKGROUND: Since 1978, two years after Genentech was founded, R.F. MacDonald Co. has provided boiler room equipment and field service for this expanding bio-technology industry leader. We have furnished over twenty Cleaver Brooks boilers for Genentech’s steam and hot water requirements. These include firetube and commercial watertube boilers.
We
have also been awarded an open-ended contract for ongoing pump repairs,
including Goulds pumps which R.F. MacDonald Co. exclusively represents.
PROJECT: Retrofit two existing Cleaver Brooks 400 HP firetube boilers to comply with Bay Area Air Quality Management District (BAAQMD) Best Available Control Technology (BACT) emissions requirements and upgrade combustion controls and flame safeguard with state-of-the-art Cleaver Brooks HAWKTM Boiler Management System.
REQUIREMENTS: Convert the existing boilers to meet the BAAQMD emissions requirements of 25 ppm NOx and 50 ppm CO.

- Special 24” Combustion Air Impeller
- 30 HP Blower Motor
- Cleaver Brooks High Turndown Burner Assembly
- Induced Flue Gas Recirculation Damper System
- New Motor Starter, Fuses and Overloads
The major functions and features of the Cleaver Brooks HAWK™ Boiler Management System, which was also installed as a part of this project, are:
- Utilizes solid state control and limit sensors. Unlike conventional controls, these controls provide enhanced safety since they cannot be jumpered. First out annunciation and diagnostics of 73 separate faults are monitored and unit self tests for proper operation.
- Boiler start cycle delayed release to automatic firing rate modulation to reduce thermal stress.
- Non-volatile lockout and history files with last (6) lockouts readable through integral LCD display.
- Unique characterization to the specific boiler the HAWK™ is installed on for firing rate control, cycling control, and system prepurge.
- Capability for remote or local communications to a personal computer including the capability to change non-safety related parameters remotely.
- Continuous monitoring of all applicable sensors, including steam pressure, gas pressure, and oil pressure to ensure signals are within operating range.
- Automatically returns the burner to the low fire position before shutting off when power is interrupted.
These Cleaver Brooks boilers, upgraded by R.F MacDonald Co. field service technicians, are now providing Genentech with enhanced safety, additional diagnostic capability for improved operation, and a simplified emissions control system for environmental compliance.
