Safe Operation and Troubleshooting of CB-HAWK Boiler Management Control System. This system is used on most types of steam or hot water boilers, including fire-tube, industrial water-tube, and commercial water-tube. The control system is designed to operate a gas, oil, or combination burner using a single modulation motor and provides the best results when used with a fully modulating burner.
Steam boilers designed for 15 psig and hot water boilers designed for 250 ° F at 125 psi or less are constructed in accordance with Section IV, Power Boilers, of ASME Code. Steam boilers designed for operating pressures exceeding 15 psig are constructed in accordance with Section 1, Power Boilers, of the ASME Code.
Each boiler is capable of firing natural gas, oil and/or waste gas, in order to supply the plant header with 1,365 psig steam at a maximum capacity of 310,000 lb/hr. The project team included the end client task force at the manufacturing facility, the engineering firm with design/procurement responsibility, the boiler OEM, the burner/gas train OEM, and the safety instrumented system consultant.
Boilers consist of a number of tubes that carry the water–steam mixture through the furnace for maximum heat transfer. These tubes run between steam-distribution drums at the top of the boiler and water-collecting drums at the bottom of the boiler. Steam flows from the steam drum to the superheater before entering the steam-distribution system.
Hot Water Boiler Sequence of Operation Aquastats - As boilers go, there is not a single sequence of operation for any hot water boiler out there, but there is a typical sequence of operation for most boilers.
