STEAM HEATER Russian patent published in 2014 - IPC E04H15/10 

FIELD: personal use articles.

SUBSTANCE: invention relates to devices intended for satisfaction of man's vital needs. Proposed is a method for heating tourist tents and other spaces with campfire heat transmitted into the tent by way of water steam. The design represents a slanted metal tube (3) with a dead bottom end to be placed into campfire flame (4) and a heat exchanger made of polymer material (2) at the other end positioned inside the tent (1). The tube is made as a single piece or composed of sections tightly connected to each other; its dead end is placed into the campfire flame and contains a small quantity of water (5) filling the heated tube part. The other end is connected to the heat exchanger and placed inside the tent. The tube length must be sufficient to ensure fire safety; the tube is placed at a small angle relative to the horizontal. The heat exchanger is made of 0.3-0.5 mm polymer material (PE, PVB, PUR etc.) in the form of a monolayer or reinforced with textile. The heat exchanger is a bag of rectangular or other shape with fittings for attachment to the tent frame in the top part and a hole for tight connection to the tube in the bottom part. For a 2-4-men tent, the heat exchanger sizes are determined by the tent wall size and may be equal to 1-3 m (length) and 0.8-1 m (width/height). The heat exchanger must be installed in the tent so that to ensure free drain of condensate back into the tube.

EFFECT: improved heating.
