Continuous operation time
The time that the burner is able to work without changing the cylinder or refilling the tank. Usually, the characteristics indicate the operating time at maximum power (see above); at lower power, the actual operating time may be longer than stated. However, it is best to evaluate and compare different models by directly claimed battery life.
Another important nuance is that battery life directly depends on the volume of the fuel tank — and many modern burners are designed for interchangeable cylinders produced in different volumes. Therefore, the characteristics may indicate for which cylinder model the continuous operation time is given (and for
multi -fuel models, the type of fuel should also be specified). If there are no such data, the tank capacity required for a certain time can be calculated from fuel consumption: for example, gas consumption of 180 g / h and battery life of 120 min (2 h) mean that the data are given for a cylinder of at least 360 g (400 mL) gas. With other volumes, the time of continuous operation will differ accordingly.
Refueling capacity
The maximum amount of fuel that can be placed in the burner in one refueling. This parameter is relevant mainly for liquid and multi-fuel models (see "Fuel"), it corresponds to the working volume of the tank (complete or
built-in). At the same time, a larger tank allows you to work longer without refueling, but it affects the dimensions and weight of the entire structure. Therefore, its volume is chosen depending on the performance in such a way that one filling is enough for at least 1.5 – 2 hours; in lamps and compact heaters (see "Type") the battery life can be much higher.
Case included
The presence
of a cover in the delivery set of the burner. The cover will be useful during transportation and storage: it will protect the device from various negative impacts and reduce the risk of losing components (after all, burners are often stored and transported unassembled). For this purpose, impromptu packaging can also be used, however, a complete case that is optimally suited for the burner will be more reliable and practical. In addition, in models with a cooking container (see above), the cover can also play the role of a heat-insulating casing, which allows you to transfer the device right during the cooking process.
Weight
The total weight of the device. Usually, the specifications indicate "dry" weight — excluding fuel.
Lightness is important on long hikes where you have to carry your gear; on the other hand, ceteris paribus, less weight means either low strength and reliability, or greater cost. The lightest classic type burners and lamps (see "Type") weigh
up to 200 g, in the working position, most of the mass of such a device falls on fuel. However, there are also more massive models. For plates, in turn, lightness is not critical, and most of these models are quite heavy —
1 kg or more. In heaters, the weight can be different — from 60 – 70 g in pocket hand warmers to 1.5 kg (or even more) in powerful outdoor appliances.
