Shroud for space heater

Abstract

A shroud is used to encompass a space heater ordinarily used within a tent or shelter. The shroud allows the space heater to be used outside the tent or shelter.The shroud is made from a series of components and is readily disassembled to allow compactness for storage or moving. The shroud is positioned over the space heater and ambient air is drawn into the spaces between the shroud and the heater where the air is heated by the heater. The heated air leaves the shroud through a duct when extends to the tent or shelter sought to be heated.

Description

INTRODUCTION[0001]This invention relates to a shroud for a space heater and, more particularly, to a shroud for a space heater which will allow use outside a shelter for such a heater which heater is normally used inside a shelter when the shroud is not in place.BACKGROUND OF THE INVENTION[0002]Diesel or fuel powered space heaters are generally used in applications where power is unavailable. Fuel is delivered to the burner of such space heaters usually via gravity and the fuel so delivered is ignited manually. Following ignition, the space heater provides heat to the shelter.[0003]A vent or draft is provided to allow air within the shelter to enter the burner combustion area of the heater. This air is combined with fuel and combusts within the burner thereby heating the casing of the heater. The combustion air is exhausted through a stack in the shelter and the non-combustion air within the shelter is heated by radiation from the casing of the heater. The heater works quite satisfa...

Benefits of technology

[0007]According to one aspect of the invention, there is provided a shroud for a space heater used for combusting fuel with the combustion products exiting the heater through a stack and combustion air entering the heater through a heater intake, a casing surrounding the heater which casing is heated by combustion within the heater and which casing radiates heat to the atmosphere, said shroud enclosing a significant portion of said space heater and allowing ambient air to circulate between said casing of said space heater and the inside of said shroud and to therefore become heated ambient air, an exit port formed in one end of said shroud to allow said heated ambient air to exit said shroud and to enter into a duct operable to extend to a tent or shelter and to discharge said heated ambient air into said tent or shelter, said shroud being removably positioned on said heater for facilitated installation or removal thereof, said shroud further having a door which may open or close to allow the commencement of combustion within said heater.

Problems solved by technology

In addition, it is always possible to accidentally dislodge the heater and overturn it.

Although the SHA heater is designed to provide only a small amount of free fuel if the heater is overturned, even a small amount of spilled fuel from a hot heater can be hazardous and result in a fire.

However, if the SHA heater is located outside the tent, the heat generated by the combusted fuel will dissipate into the atmosphere without reaching the interior of the tent or shelter.

This is, of course, disadvantageous particularly in low temperatures.
