<p>The heater is for rooms used by personnel, the heat being generated by chemical reaction between two or more agents, generating a gaseous product. It uses agents whose reactive product does not have a suffocating effect or is detrimental to health. The product can have a dew point below which it falls for part of the path, along which it travels inside the heater. The agents can be delivered into the reaction chamber only in the correct proportions, and the chamber is typically gas-tight.</p> |
