Chicago Fire Commissioner Robert Hoff is stepping down, marking a significant change in the city's emergency management leadership. The news was first reported by CBS Chicago, which noted that Hoff, one of the last remaining figures from the Daley administration, submitted his resignation on Wednesday. He will be replaced by Jose Santiago, who previously served as the head of the Office of Emergency Management and Communications but left the city after challenges during the Groundhog Day storm last year. Hoff, 56, has been a long-standing voice for firefighters, famously opposing any efforts to close firehouses or reduce staffing levels. His decision to resign comes on the 50th anniversary of his father’s death, a firefighter who died in the line of duty. According to sources, the move was entirely his own, and the mayor did not pressure him to leave. “He wanted to go out on his own terms,” said a close associate. “He’s ready to teach and help keep firefighters safe.” Hoff’s departure leaves the Chicago Firefighters Union without a strong advocate as they prepare for difficult contract negotiations with Mayor Rahm Emanuel. The Sun-Times highlighted that Hoff had always stood firm in his support for the department, even when it meant going against city officials. His resignation has sparked mixed reactions, with some expressing disappointment and others understanding his need for a fresh start. At a recent union meeting, Local 2 President Thomas Ryan confirmed Hoff’s planned exit, stating that the commissioner had told him “it was time to go.” As the city adjusts to this change, the future of the CFD remains uncertain, with new leadership set to take the helm soon.

Ammonia cracker

Ammonia cracker of XRAQ(FC)series takes liquid ammonia as the source material ,and when heated, decomposes into the mixed gas of 75% H2 and25% N2 under the action of catalyst.


Some of the usages of Ammonia cracker of XRAQ series:

1) It is used as the protective gas in the furnace which produces and processes the black metal, on-ferrous metal, metal plate, strip, wire material tubing and standard parts of machinery.

2) It is used as the shielding gas of tinning bath in the float glass production.

3) It is applied to the sintering circuit of cemented carbide and powder metallurgy.

4) It is applied to the sintering of high-temperature refractory (such as silicon carbide, silicon nitride)

5) It is used as the reducing gas in chemical industry.

6) It is used for deoxidization by hydrogenation in the nitrogen purification.

The Advancement of XRAQ(FC) series:


1)Low cost:Device of XRAQ(FC)series is an easy way to get the mixed gas of N2 and H2.Compared with hydrogen generation device by water electrolysis, it possesses the advantage of low investment, simple structure and easy operation.

2)Reliable Performance: Temperature is controlled by automatic temperature controller; flow rate is regulated by valves; no need of specially trained operators; stable gas can be get consecutively.

3) High quality catalyst, stainless steel that is heat and corrosion resistant, nickel chrome electric heating element are selected to use, which prolongs the service life.

4) Strong technological team and high-quality after-sale service. When installed on spot, the only thing to do is to connect the gas source and power. Excellent electrical and mechanical assembly technology; Continuous technical services are provided; Responsible for on-site commissioning and training.
