The fire emoji represents a streak. A streak in snapchat is defined as three days in a row in which you and a friend snap eachother. The number next to the streak tells you how many consecutive days you and a friend have snapped eachother. The fire emoji streak will appear when you have snapped three days in a row.
UPDATE: As of 4/08/2017 the longest Snapchat streak in the world is 977. The current official world record for Longest Snapchat Streak for IOS/Android as of 10/11/2016 is 798 days. Contrary to many other sources (where longer streaks are hacked or falsified), this is the official Snapchat Inc. information.
