Recuperative Gas Burner System • Increased efficiency and fuel economy  • Under cold start conditions, unit can fire at up to 50% extra to maximum hot air rating for rapidheat-up • Wide stability limits and excess air and gas capability • Easy installation • Rugged construction • Up to 30:1 turndown • Excess air/gas ratio options OPERATION The Nu-way Multiplex recuperative burner system offers the option of a self-recuperative burner or a separate recuperator and burner.Therecuperative system is designed to extract waste heat from the flue products of medium to high temperature industrial processes and to pre-heat the cold combustion air, returning heat to the process and so considerably reducing the fuel usage. The system is designed for the modernisation of existing furnaces or for use in new, energy-efficient furnace designs. Applications include forge furnaces, reheating furnaces, intermittent kilns, soaking pits, heat treatment furnaces, crucible furnaces and indirect heating processes. Self Recuperative Burner • Eliminates insulated duct work |
Multiplex 20 kW-12 MW MP Series Gas, Oil and Dual Fuel Burner  • Exceptional flame stability • Wide turndown (up to 30:1) • Low air and gas pressure requirements • Inner assembly easily removed • Combustion tunnel options, heat resistant metal, refractory, silicon carbide • Low, medium and high velocity options • Excess air/gas ratio options. The MULTIPLEX burner has been designed to achieve a high degree of stability over a wide turndown range from relatively low service inlet pressures. The complete operating range of the standard burners at required pressure is given in the information included in this data sheet. Gas and air flows may be controlled by a gas proportionator and air butterfly valves, or for maximum turndown, controlled by a mechanical or electronic ratio control system. For high excess air operation the air valve would normally be left fully open and controlled by the gas valve only, thus providing a relatively constant volume of combustion products in the furnace throughout the operating range. BASIC BURNER The basic burner is supplied without a combustion tunnel. It is suitable for mounting directly to the wall of the application, the combustion tunnel being formed by a suitable hole in the furnace wall. FUEL Burners can be supplied for all commercial gases, (light) oil, or dual fuel. COMBUSTION TUNNELS Multiplex burners are available with a number of combustion tunnel materials and the following is intended only for general guidance. All sizes, in all materials, can be supplied with extended projection. METAL COMBUSTION TUNNELS For low temperature applications up to 450°C, standard stainless steel material can be used for the combustion tunnel. For high temperature applications up to 900°C, a high quality heat resistant stainless steel is available.

Multiplex 20 kW-4.4 MW FMP Series Packaged Industrial Process Gas Burner • Fully automatic packaged assemblies  • On/off, high/low or modulating control • Up to 20:1 turndown • Fan scroll up (standard) or down. Valve train right or left (other arrangements to special order) • Can be wired to terminal box for use with separate controls • Combustion tunnel options, heat resistant metal, refractory, silicon carbide • Excess air/gas ratio options • Low and medium velocity options • Continuous running fan to prevent over-heating when burner not in operation (optional) OPERATION  |
Multiplex 20 kW- 4.4 MW MPHA Series Hot Air Gas Burner  • Preheated air up to 700°C • Exceptional flame stability • Wide turndown up to 30:1 • On ratio, excess air or excess gas operation • Low air and gas pressures • Inner assembly easily removed • Range of eight burner sizes giving maximum nominal outputs of 60 kW to 4.4 MW OPERATION The MULTIPLEX hot air burner has been designed to achieve a high degree of stability over a wide turndown range from relatively low service inlet pressures. The complete operating range of the standard burners at required pressure is given in the information included in this data sheet. Gas and air flows are normally controlled by double diaphragm proportionators measuring mass flow of air and gas to compensate for air temperature variations. FUEL Burners can be supplied for all commercial gases, (light) oil, or dual fuel. REFRACTORY COMBUSTION TUNNEL These burners are usually supplied with high temperature refractory quarls suitable for temperatures up to 1700°C. |
Energystream 100 kW-20 MW ES/ESX Nozzle-Mix Gas Burner  • High output capacity up to 600 kW per 300mm • Wide turndown range • Versions available for fixed air/gas ratios (including stoichiometric) and gas only control • Modular construction based on nominal 152mm and 305mm increments with tee and cross elements • Minimum service maintenance • Available in package forms with or without combustion air fan • Side or rear air inlet for combustion air fan versions to suit customers’ application The Nu-way ENERGYSTREAM burners represent a new concept in direct fired air heating. They are nozzle mixing line type modules, available in straight or cross pattern that can be built into an infinite variety of patterns to suit duct dimensions and application constraints. The basic ES burner head comprises burner section, integral pilot assembly, spark ignition and either flame probe or UV flame monitoring. The ES burner package may also include a combustion air fan and gas control train, and can be mounted onto a sideplate for ease of installation in ducts. Modulating or high/low control options are available for gas and air control, or gas only control. Combustion air for the burner would normally be provided by a blower mounted either directly to the burner head or at a position adjacent to the duct. Stainless steel casings and nozzles are additional options to allow operation at higher temperatures. |
