A multi-stage heating type heat conduction oil boiler and method thereof

Abstract

The invention discloses a multi-stage heating type heat conduction oil boiler. The multi-stage heating type heat conduction oil boiler comprises a heating furnace body. The heating furnace body is ofa horizontal type transverse furnace body structure. A left flue gas heat exchange box and a right flue gas heat exchange box are symmetrically arranged at the two ends of the heating furnace body correspondingly. A plurality of left heat exchange oil pipes and a plurality of right heat exchange oil pipes are arranged in a left heat exchange cavity of the left flue gas heat exchange box and a right heat exchange cavity of the right flue gas heat exchange box in a penetrating mode correspondingly. The multi-stage heating type heat conduction oil boiler is simple in structure; and a pre-combustion chamber structure is arranged in a furnace core and matched with an external main combustion chamber structure to achieve sextuple heating of incoming heat conduction oil, so that the heating efficiency of a heating pipe is effectively improved.

Description

technical field [0001] The invention belongs to the field of boilers, and in particular relates to a multi-stage heating type heat-conducting oil boiler and a method thereof. Background technique [0002] The heat-conducting oil boiler uses heat-conducting oil as the medium, uses the hot oil circulating oil pump to force the medium to circulate in the liquid phase, transfers the heat energy to the heating equipment and then returns to the heating furnace for reheating, and transfers the heat energy to the heating equipment and then returns to the heating furnace for reheating. , it has the ability to obtain high working temperature under low pressure, and can control the operation of medium with high precision; however, the existing boiler furnace body is mostly a single combustion chamber furnace body, and in a single combustion chamber, the flame often flows from One end is sprayed to the other end, and the flame near the flame nozzle has a high temperature due to sufficie...

Problems solved by technology

[0002] The heat-conducting oil boiler uses heat-conducting oil as the medium, and uses the hot oil circulating oil pump to force the medium to circulate in liquid phase, transfer the heat energy to the heat-consuming equipment and then return to the heating furnace for reheating, and deliver the heat energy to the heat-consuming equipment before returning to the heating furnace for reheating , with high working temperature under low pressure, and high-precision control of medium operation; however, the existing boiler body is mostly a single combustion chamber furnace body, in which the flame often flows from One end is sprayed to the other end, the flame near the flame nozzle has a high temperature due to sufficient oxygen and fuel, and the flame temperature far away from the flame nozzle is relatively low, and the unevenness of the front heat and the rear cooling is obvious, and it is a single combustion chamber, which is easy to burn. Insufficient combustion is a waste of resources. At the same time, due to the existing ordinary cylindrical combustion chamber, the heating efficiency of the heating tube is not high, and a lot of energy escapes through the flue gas.
