Energy-saving oil-combustion hot-air furnace

Abstract

The invention relates to an energy saving fuel oil hot air oven, characterized in that it mainly comprises combustion chamber, heating room and fan; the heating room is an air heating channel, on which there are air inlet and air outlet; the fan is located on the flowing path in the heating room so as to make air flow from the air inlet to the air outlet; the combustion chamber is set in the heating room and there is an air flow space between the periphery of combustion chamber and the wall of heating room; the combustion chamber is a cylinder combustion room; one end is igniting end connected with adding fuel burner and the other end is closed as fireproof plate and reversal combustion end; a group of heat dissipation holes are set on the peripheral wall of cylinder at the igniting end evenly and a group of noise damping holes are set on the peripheral wall at the fireproof plate and reversal combustion end evenly; the hole diameter of said heat dissipation hole is larger than the one of noise damping hole. The invention makes flame burn secondly in the combustion chamber and burning is sufficient. Heat quantity after burning can be discharged directly to firing or drying so that it is more energy saving and heat efficiency can achieve 95% or so. It is provided with simple whole structure and convention manufacture.

Description

technical field [0001] The invention relates to a heat source device for preparing hot air, in particular to a fuel-fired hot air stove, which is widely used in baking and curing of coating technology, drying of tobacco, drying and molding of wood, shaping and drying in textile printing, dyeing and finishing industries, etc. Process occasions with air heating. Background technique [0002] In industry, there are many process occasions that require hot air heating and drying: such as baking and curing of coating process, drying of tobacco, drying and molding of wood, etc. The hot blast stoves used in these occasions are divided into oil-fired hot blast stoves according to the difference in heating energy. , Gas stove, etc. [0003] Because the gas hot blast stove burns natural gas, liquefied petroleum gas and other gases, less flue gas is produced during combustion, so the direct-fired structure can be adopted in structure. The hot air is generated by the combustion of the ...

AI Technical Summary

Problems solved by technology

[0004] The present invention solves the technical problems existing in the prior art that the combustion of fuel oil is not sufficient and produces a lot of smoke, so that only the heat exchange structure can be used, the thermal efficiency is low, energy saving is not, and the structure is relatively complicated, making it more difficult to manufacture. Combustion sufficiency and flue gas reduction are studied to provide a new type of energy-saving fuel-fired hot blast stove
