Aircraft
Cruising at FL370; the aircraft lost cabin pressurization. We complied with all our immediate actions items; QRC; and QRH Checklists. We started to initiate an emergency descent to 10;000 feet MSL because we were unable to control the cabin. [Advised] Center. We advised Dispatch of our situation. We had enough fuel onboard to continue to [destination]. As we leveled off at 10;000 feet MSL; we started to get a burning smell in the cabin and cockpit; so we then advised Center we needed to divert immediately. We were right on top of [a suitable alternate]. We advised Dispatch now we are diverting there due to the burning smell. We amended our Release; did all our checklist and landing data. We landed within eight minutes. I made the announcement to the Flight Attendant and passengers to remain seated and not to evacuate. Fire rescue was waiting for us. After landing; we had fire rescue access the aircraft. After that we taxied to the terminal and parked at a gate to offload our passengers. First Officer and I worked very well together. He flew and talked to ATC while I coordinated everything else. We were able to do all our checklists in that short time.
