The invention relates to heating, more particularly to domestic stoves which are not restricted to the use of solid fuel only, and even more particularly to multi-fuel stoves that run on liquid, solid and gas fuels, inter alia collapsible stoves and field stoves for providing warmth for personnel, using any type of fuel. The technical result is an increase in the functional capabilities of field stoves and domestic heating stoves, due, inter alia, to portability, since they can be delivered by any means of transport, including being dropped from a helicopter, and are easy to convert from a travel configuration into a working configuration, and the universality of the liquid burners, which are capable of functioning on the basis of compressed air from an external source (supercharging), making it possible for such stoves to be used by outdoor maintenance crews, in forges or for heating solid, shaped parts prior to welding. Furthermore, the stoves are safe to use, inter alia, in canvas tents and on timber flooring, and demonstrate greater efficiency irrespective of whether liquid or solid fuel is used. The present multi-fuel stove is designed to be collapsible and comprises a smoke collector (2) and a housing (1). The upper portion of the housing (1) contains a piston (3) which is positionable and movable along the vertical axis of the housing (1). A burner (6) with an evaporator cup (8) is designed to be received in the lower portion of the housing (1). The burner (6) with an evaporator cup (8) is removable, leaving a space for solid fuel.
