Combustion chamber structure of fuel oil heater

Abstract

The invention relates to a combustion chamber structure of a fuel oil heater. The combustion chamber structure comprises an inner net, an outer net and an outer cover. The inner net comprises an upper top bowl, an upper inner net body and a lower inner net body which are connected together in sequence. The outer net, the outer cover and the lower inner net body are fixed together through a connection bolt in a penetrating mode. The combustion chamber structure is characterized in that a fluid director is arranged in the center of the lower inner net body; the fluid director is provided with a cylindrical flow guide net and a lower top bowl fixed to the top of the flow guide net; distribution air holes are uniformly formed in the flow guide net; and a connection bolt penetrates through two of the distribution air holes for fixation and positioning. According to the combustion chamber structure, through the accurate design of the inside and the outside, oxygen supply on the two sides of flames of a lamp wick is sufficient; and the gas pressure is kept balanced relatively, the gas flow is uniform and gentle, the chimney effect of the inner net is effectively overcome, the flames are more stable, the content of CO in the smoke is low, and the requirements for indoor heating and long-term use safety are met.

Description

Technical field: [0001] The invention belongs to the field of fuel oil heaters, and in particular relates to an improvement in the structure of a combustion chamber of a fuel oil heater. In particular, a gas deflector is added to the lower internal net to distribute more gentle and uniform oxygen to the flames to meet high-efficiency combustion. Background technique: [0002] The combustion chamber of a fuel oil heater generally includes an inner net, an outer net and an outer cover, such as image 3 , the wick 5 faces the gap between the inner net 1 and the outer net 2, the inner net stands on the top of the wick tube, the outer cover 3 mainly plays a protective role, and there is no ventilation hole; the inner net 1 and the outer net 2 are densely covered with a vent hole, In order for the air to enter from both sides of the wick flame, it is necessary to prove the oxygen supply for combustion; the oxygen supply on the side of the inner net is inflowed upwards from the bott...

AI Technical Summary

Problems solved by technology

The existing inner grid is a straight-through structure, which is only controlled by slightly narrowing the diameter of the upper inner grid, which cannot overcome the chimney effect formed by the cold and warm air flow. The added upper top bowl can distribute the airflow around the upper inner grid, but the lower inner grid The air pressure or flow at the net is still insufficient, resulting in sufficient oxygen supply in the upper part and a slight shortage in the lower part, which is also the root cause of the CO content in the flue gas; how to further reduce the CO content in the flue gas is not only the subject of the present invention. The object is also the goal pursued by the industry
