HOME > English > Products > HRS Burners

A simple compact direct firing regenerative burner incorporating NFK's latest high temperature combustion technology. With a built-in ceramic honeycomb regenerator this unit achieves ultra-high efficient heat recovery, drastic reduction of Nox emissions and uniform temperature distribution.

【Applications】

・Various types of re-heating and heat treatment furnaces
・Casting and forging furnaces
・Ceramics firing furnaces
・Ladle pre-heaters

 

Detail

鉄鋼加熱炉への適用(HRS-DLバーナ)
Application of HRS-DL Burner
for Re-heating Furnace at Steel Mill

A non-oxidizing and reducing type of regenerative burner whici is the practical application of high temperature combustion technology in partial combustion (air ratio < 1.0). The maintenance free design of the honeycomb regenerators minimizes soot particles and is effective for environmental conservation.

【Applications】

Reheating furnaces for steel and copper, ceramic calciners.

 

HRS-DFバーナハニカム型蓄熱式無酸化・還元燃焼システム
HRS-DFバーナハニカム型蓄熱式無酸化・還元燃焼システム

A burner with a built-in honeycomb regenerator specially designed for the applocation of ultra-high pre-heated air combustion technology for heat treatment processes and other purposes in iron and steel manufacturing.

Minimum pressure loss and low NOx emission can be achieved simultaneously. Continuous forced cooling of the radiant tube is also possible.



【Applications】

Atmospheric furnaces and various types of indirect heating furnaces.

HRS-MD-RT Burner
HRS-MD-RTバーナ低圧損型蓄熱式ラジアントチューブ燃焼システム

A compact direct firing burner with a built-in honeycomb regenerator which incorporates ultra-high pre-heated air combustion technology to achieve minimum pressure loss and low NOX emission simultaneously. The built-in block type honeycomb regenerator allows for easy maintenance and servicing of regenerator media.

【Applications】
・Heating furnaces
・Ceramic calciners
・Steel re-heating furnaces.

優秀省エネルギー機器 2008; Received The Chairman's Award of Energy-Efficient Machinery Award from The Japan Machinery Federation
(UR Burner)

A continuous fueling, direct firing burner with a built-in honeycomb regenerator which imcorporates ultra-high pre-heated air combustion technology to achieve both minimum pressure loss and low NOX emission. The built-in block type honeycomb regenerator allows for easy maintenance and servicing of regenerator media. An additional fuel nozzle for off-gas combustion may also be installed.



【Applications】

・Hydrogen generators
・Indirect type reforming furnaces

HRS-UXバーナ
HRS-UX Burner

With this unit, it is possible to continuously generate high temperature air or steam (1,300K-1,500K) with maximum pressure of 10KPa by application of ultra waste heat recovery system utilizing the ceramic honeycomb. This steam enthalpy intensifier is used in the biomass gasification process developed by KTH (Royal Institute of Technology, Sweden) and other gassification processes.

高温空気/蒸気発生装置

CEM is for the operation of two sets (one pair) of regenerative burners. The four way valve makes possible both air feeding and flue gas exhaust with a single exchange valve.

The advantages of CEM in comparison with conventional valve system (four sets of valves required) are follows:

  • Low cost

  • Small size and simple construction

  • Simple piping and easy control

  • Small leakage ratio (below 5%)
  • Natural air cooling

High Temperature / Pressure Indirect Hot Air Generator
(TN400・TN700)

Developed in collaboration with TOHO Gas Co.,Ltd., this hot air generator can generate hot air or steam at 400℃ or 700℃ by means of a highly efficient regenerative burner for heating and straight through type finned tubes for the heat exchanger. Operation cost is about 1/3 that of conventional electric heating systems.

Model number:TN400・TN700
Applications:Metal Mold Heating Furnaces
                    Tempering Furnaces
                    Paint Baking Driers
                    Rubber Vulcanizing Furnaces
                    Solvent Driers.
