It's quiet now at the scene of the fire on 9400 Halsted Street. The building is a two-story brick structure. So far, reports confirm one victim has not survived. Initial responders arrived to find a woman already deceased upon arrival, while an adult male remains unaccounted for.
As firefighters worked to extinguish the blaze, they noted the intensity of the flames made it impossible to safely attempt a rescue for the missing man. The roof sustained significant damage, and there were no audible smoke detectors heard by crews as they entered the premises.
Firefighters have since cleared the immediate danger but plan to re-enter the building early tomorrow morning with hand tools to thoroughly search for any remaining hazards or hotspots. CFD teams expressed their condolences to those affected and emphasized the importance of having working smoke alarms in homes.
In a follow-up effort, the Chicago Fire Department will distribute smoke alarms in the surrounding area starting at 10 a.m. tomorrow. This initiative aims to ensure neighbors are better equipped against potential emergencies.
For now, the investigation into the cause of the fire continues. Photos from the scene show heavy structural damage, with charred remnants of what once stood as a residence. The community is urged to stay vigilant and prioritize safety measures like installing and maintaining smoke detectors.

Block heat exchangers are compact, modular heat exchange devices classified based on materials, structural designs,
application scenarios, and manufacturing processes. the structured summary of classification as below: Classification by Material
1. Graphite Block Heat Exchanger - Structural Features: Made of impregnated or molded impervious graphite, offering high corrosion resistance and
thermal conductivity. Common types include cylindrical block-type (e.g., Cylindrical Block Graphite Heat Exchanger)
and shell-and-tube graphite heat exchangers. - Applications: Ideal for corrosive media like strong acids or alkalis, such as heat exchange in phosphoric acid production. 2. Ceramic Block Heat Exchanger - Structural Features: Fabricated from monolithic ceramic blocks with elongated cross-sectional channels. The overlapping
arc-shaped channel walls enhance fluid flow efficiency. - Applications: Suitable for high-temperature or high-wear environments in chemical and energy industries. Classification by Structural Design
1. Block-and-Hole Heat Exchanger - Composed of multiple perforated graphite blocks stacked together, allowing fluid exchange through interconnected channels (e.g., *Cylindrical Block Graphite Heat Exchanger*). 2. Shell-and-Tube Block Structure - Modular shell-and-tube designs, including fixed-tube and floating-head types. Examples include *Complex Shell-and-Tube Graphite Heat Exchanger*. 3. Monolithic Block Heat Exchanger - Single-piece structures formed by casting or injection molding, eliminating welds and enhancing pressure resistance (e.g., ceramic or metal monolithic blocks). Classification by Special Functions
1. High-Pressure Thread-Locked Ring Heat Exchanger - Design Features: Employs threaded locking rings for sealing, suitable for high-pressure hydrogen environments (e.g., hydrogenation reaction systems). Corrosion resistance is improved via optimized materials like hydrogen-resistant steel. 2. Corrosion-Resistant Block Heat Exchanger - Examples include *Double-Side Corrosion-Resistant Cylindrical Block Graphite Heater*, designed for strong acid media. Classification by Manufacturing Process
1. Modular Assembly Type - Multiple modules connected via bolts or adhesives, facilitating maintenance (common in graphite heat exchangers). 2. Integrated Monolithic Type - Molded in one piece for high structural integrity, such as cast ceramic or metal blocks. Application Scenarios
- Chemical Industry: Graphite and ceramic block exchangers handle corrosive media (e.g., sulfuric acid, phosphoric acid). - Energy & High-Pressure Systems: Thread-locked ring exchangers are used in petroleum hydrogenation and high-pressure steam systems. - High-Temperature Environments: Ceramic blocks excel in waste heat recovery from high-temperature exhaust gases.
