TUNABLE FLAMELESS HEATERS

摘要

A flameless heater apparatus and method whose heating performance can be selected and tuned at the time of manufacture, and which is easily used and has a long shelf life. The apparatus and method may be used in flameless ration heaters, such as may be used in military or emergency situations. There is provided a flameless heating method and apparatus in which the solid reactive ingredients are not all blended or mixed together at the time of apparatus fabrication. Rather, at least one key ingredient in a dry powder form is kept physically segregated from all the other ingredients, such as catalysts and surfactants. The catalyst and the active ingredient do not come into effective contact until a flowing aqueous solution carries a reactive catalytic-saline solution to the active ingredient alloy, and then mixes the inter-reactive ingredients to generate the desired heat.
