High-efficiency and energy-saving hot blast stove

Abstract

The invention relates to a high-efficiency energy-saving hot air stove, which comprises a furnace body, a grate is arranged in the furnace body, a hot gas output pipe is connected to the furnace body, one end of the hot gas output pipe is connected and arranged on the top of the furnace body, and an The furnace wall extends and increases the exhaust chamber, and the other end of the hot gas output pipe is connected to the hot gas inlet before the heat exchange of the heat exchange mechanism. Atmospheric inlet connected to the first hot gas outlet. The invention overcomes the severe heat loss and high operating cost of common steam boilers and heat conduction oil boilers in the prior art, and the heat conduction oil intermediary is easy to burn when transferred under high temperature conditions, and the steam is easy to explode under high pressure, which has serious safety problems. The defect of hidden danger, through the above design, has the advantages of compact structure, complete combustion, high heat production efficiency and heat exchange efficiency, and safe and reliable operation.

Description

technical field [0001] The invention relates to a high-efficiency and energy-saving hot blast stove. Background technique [0002] In the process of industrial and agricultural production, a large amount of heat is required to process various production materials such as drying, forming, and solidification, and its equipment only depends on steam boilers or heat-conducting oil boilers. The above two boilers generate heat by the furnace, and the heat is transferred to the intermediary (water or oil) in the pot. The intermediary is transported by steam pressure or by a circulating pump to the drying box or drying line, and then exchanged by a heat exchanger. , to bring the heat and air flow to the drying place to achieve the purpose of material drying. [0003] The heat production operation procedure of the heat transfer oil boiler is to provide a large amount of fuel to the furnace for combustion, and generate a large amount of heat to transfer to the heat transfer oil in th...
