The Control of Boilers 2nd Edition by SAM G. DUKELOW. In the book sections and subsections covering interlocks, burner start-up and management, and the management of the start-up and operation of pulverizers and other fuel burning equipment. Along with this is the recognition of applicable safety codes of the National Fire Protection APPLICATION NOTE 1 CCYS-G-01A 03-99 OVERVIEW The boiler combustion control system is designed to maintain a proper air/fuel mixture under varying load conditions and within safe limits. The system should provide nearly complete fuel combustion as efficiently as possible. Discussions here are limited to oil and/or natural gas fired industrial boilers. Control systems that perform these

specification of combustion control systems for drum-type fossil-fueled power plant boilers. 2 Scope 2.1 The scope of this standard is to address the major combustion control subsystems in boilers with steaming capabilities of 200,000 lb/hr (25 kg/s) or greater. These subsystems include, but Heating and process boilers can be one of the most critical pieces of machinery at your facility, and they require properly maintained safety controls to ensure safe operation. Because boilers are fuel-fired and heated by combustion, there is a risk of explosion and fire that can destroy your equipment, and facility.

The volume and nature of emissions from combustion in boilers differ depending on fuel composition, fuel consumption, boiler design and operation and pollution control devices used. Independent of fuel used, the general process of combustion is as follows: Figure 1: Process for combustion in boilers Design Specification For Boiler Control System Prepared By Fenton Systems, Inc. 28054 Center Oaks Court Wixom Mi 48393 248-374-5551 for DSBoiler V1.0 November 12, 2003 .

Automatic Combustion Control in Boilers Request PDF. Combustion Control Problem Until recent years, only the largest boilers could justify sophisticated combustion controls. Now, higher fuel costs and occasionally limited fuel availability make it necessary for users to improve boiler efficiency. Government regulations force compliance with stringent air pollution and safety standards. Combustion, launched its boiler combustion solution in November 2015. The adoption of ultra-low excess air ratio com-bustion control (a technology previously not possible) has enabled the improvement of boiler combustion effi-ciency and the reduction of boiler fuel costs by approxi-mately 1%. 2.
