Combustion Engineering Solutions - Boiler Applications

  1. 1. JB 400 Boiler Applications JB 400 Boiler Burners series are typically used in oil/gas/dual fired boiler applications. They are designed and built in rugged construction to supply an intensely mixed air fuel mixture into a furnace for maximum combustion effectiveness. This thorough mixing is achieved by the adjustable rotational air momentum & fuel injection pattern. This burners are suitable for different type of atomizers and gas. Salient Features: • Customised oil fired burners in dual block construction complete with instrumentation & automation. • Burners Mounting arrangement as per different design of various boiler OEM's. • Burners designed for combustion air control through common wind box, or individual damper control. • Burner mounting on boiler for uniform heat distribution through out the furnace so as to facilitate heat transfer in convection zone. • Selection of flame length and flame diameter based on furnace length and width so as to avoid flame impingement on furnace walls. • Oil Gun can be removed while burner is in operation. • Gas/Air High Tension, High Energy Arc ignition systems are available for hazardous applications. • Can provide solutions to improve efficiency and reduced emissions. Fuel Handling Systems Optimally designed auxiliary equipments are essential to guarantee optimal performance of the burners. The right Instruments, piping material selection and process valves are selected as per the requirement for the application. Our fuel valve trains are designed for burner start/stop operation in compliance with International standards such as NFPA 85. Combustion Engineering solutions Electric Oil Heaters Fuel Oil Valve Trains For the satisfactory Burner operations the fuel flow to the burner should have pressure, flow, temperature & viscosity calibrated as per the design. We design, manufacture & supply the Fuel Valve trains to suit the requirement of the application. The Fuel Oil Trains are designed for almost all liquid fuels such as Furnace Oil. LDO, LSHS, HSD, Coal Tar, Naphtha spent & Sludge Oil. We use best of the instruments from internationally acknowledged suppliers for the measurement & control of temperature, pressure, flow & shut off applications. The Valve Trains are used for optimum pressure drops. These trains are assembled on free standing structures for easy installation. Gas Valve Trains Jasubhai manufacture Gas Trains for burner applications. The Gas Trains include:
  2. 2. Oil Valve Train mounted at site Inspection of oil valve Train at our works Panel for Zone 1 Area Classification PLC based BMS Panel Burner Management System Our extensive experience and expertise in combustion Engineering and Burner systems has enabled us to develop superior BMS incorporating sophisticated fault tolerant system architecture. The BMS integrate the operational requirement, provide innovative solution to various constraints. Salient Features: • PLC/Relay based Burner Management System (BMS) • BMS for safe Start/Stop of burners • BMS covers the interlocks for Burner Start/Stop and Furnace Purge Cycles • Memory module and cable to interface with PC • PLC communicates with DCS through modbus 485/Ethernet • Human Machine Interface (HMI) with function key or touch screen • Local annunciation on BMS Panel • Also offered with redundant - hot standby mode with processor, input/output, communication & power supply redundancy • Customised Programmes and PID control loop for automation control • Pressure reducing & regulating Valves. • Pressure Control Valve. • Flow Control Valve. • Flow measuring device. • Pressure & Temperature measurement. • Safety shut off device. To ensure reliable operations, best components from internationally acknowledged companies are used. Selection of the instrument are done as per the area clasiification of the installation considering safety aspects (Zone 1, Zone 2). Gas valves trains are designed for various gases listed: • Natural Gas. • LPG. • LNG. • Producer Gas • Refinery Gas. • Coke Oven Gas. • Blast Furnace Gas. • Hydrogen Gas.
  3. 3. Ignition System Salient Features: • Different types of ignition systems like Gas/Air Electric, high Energy Arc and High Tension. • For ignition of oil or gas burners of all capacities in industrial plants and power stations • Available in an explosion-protected design • To prevent damage of ignition tip due to exposure to high temp of flame zone, the pneumatic retraction units are provided • Special design for tilting burner Applications are in Power Station. • Ignitors for burner applications for Chemical Industries, Refineries, Cement Plants, Waste Incinerators, Steam Generators and Heating Plants etc. • Certification: GOST-r, PTB (ATEX) Flame Monitoring System Salient Features: • IR, UV+ IR without self-check features types of flame monitoring system available • Latest semiconductor technology with highest sensitivity replaces UV tube for UV flame detection • Self-checking and fail-safe as per UL 372, FM 7610 as well as EN 230 and EN 298 standards • Enclosures meets NEMA 4x (IP 67 – Protection Class) • Relay output contact for direct control of the fuel valve and for status display • Programmable flame recognition threshold • Analog output for flame intensity 0/4 - 20 mA • ATEX approved ( Ex Class 1, div 1, Group B, C & D) • Applications are in Power Station, Chemical Industry, Refineries, Cement Plants, Waste Incinerators, Steam Generators, Heating Plants etc. • Certification: DVGW, DIN-CERTCO, APAVE, UL 372, FM Class 7610, AGA: AG 210, GOST-R, PTB (ATEX) Flame Scanner Flame Scanner High Energy Arc Ignitor
