It really depends on a number of factors, such as oxygen abundance and type of fuel you're talking about. But the products are mainly Carbon dioxide, Water, nitrogen oxides, Sulfur oxides, and occasionally, Ozone molecules are produced.

It depends on whats burning, but I would say Carbon Dioxide... Please correct me if wrong
It depends on the fuel and how well it burns. For example, methane, ethane, propane, butane, petrol, ethanol, sugar, etc. will give water & carbon dioxide if burnt fully; however, imperfect burning can produce carbon monoxide or carbon. Burning hydrogen, on the other hand, produces water.
Carbon dioxide
carbon dioxide, CO2
Carbon dioxide and water.
Carbon dioxide
When a fuel burns, it undergoes a combustion reaction. Combustion has two main products. These products are water and carbon dioxide.
When a fuel burns, carbon dioxide (CO2) is predominantly produced, along with water vapor (H2O) and other combustion byproducts such as carbon monoxide (CO) and nitrogen oxides (NOx). However, the exact chemical composition can vary depending on the type of fuel being burned.
burns, detonates, oxidizes, etc.
carbon dioxide
This actually depends on the type of fuel, but often, water vapor, pollutants and energy.
