The Flames acquired Conroy from the Kings on Monday in a trade for Jamie Lundmark and two draft picks. A Pengrowth Saddledome sellout of 19,289 spectators didn't wait long to welcome Conroy back, applauding as he took to the ice for the pre-game warmups, then cheering loudly when Conroy was shown on the Jumbotron during the Canadian national anthem.
And Conroy brought the capacity gathering to its feet when he knocked a rebound past Kings goalie Sean Burke just 1:30 into the second period to open the scoring.
Conroy rounded out the scoring with his second goal of the night at 15:16 of the third and his eighth of the season, again to a wild ovation.
Stephane Yelle and David Moss had the other goals for Calgary (27-17-6), which began a four-game homestand with its sixth consecutive victory on home ice.
Mike Cammalleri scored his 20th of the season for Los Angeles (17-30-6), which has just one win in its last 10 games (1-8-1).
Moss put Calgary ahead 2-0 at 3:50 of the season, scoring his sixth goal in 18 games after deflecting Dion Phaneuf's wrist shot from the blue-line past Burke.
Cammalleri deflected Anze Kopitar's slapshot from the point on the power play to pull Los Angeles to within 2-1 just 1:35 into the third.
Los Angeles outshot the Flames 16-7 in the third but couldn't beat Kiprusoff, who made numerous great saves. Five of Kiprusoff's stops came during a 1:29 two-man advantage halfway through the period.
Then Calgary cemented the win with goals by Yelle at 14:04 and Conroy's second of the night at 15:16.
Conroy came into the contest having gone 12 games without a goal, a streak dating back to a Dec. 29 game against Calgary.
