Portable, flueless, low nox, low co space heater |
摘要 |
A flueless, portable low nitrogen oxides emissions, low carbon monoxide emissions space heater having a fuel chamber with a fuel inlet and a fuel distributor. The fuel inlet generates a swirling fuel flow within the fuel chamber. A primary air inlet generates a counter-swirling primary airflow with respect to the swirling fuel flow in a primary air chamber. The fuel distributor discharges the swirling fuel flow into the counter-swirling primary airflow thus forming a fuel/air mixture. An ignitor ignites the fuel/air mixture. A combustion chamber is sealably secured to and in communication with the primary air chamber. The combustion chamber wall has a plurality of secondary air supply holes. An intermediate shell surrounds the combustion chamber wall and forms a space between the intermediate shell and the combustion chamber wall. A secondary air inlet is in communication with the space between the intermediate shell and the combustion chamber wall. An outer protective shell surrounds the intermediate shell. A top ring plate is sealably secured to the top portions of the combustion chamber, the intermediate shell and the outer protective shell.
