Energy-saving heating furnace

Abstract

The invention discloses an energy-saving heating furnace. The energy-saving heating furnace comprises a base; a furnace body is fixed to the upper end of the base; a hopper-shaped shell is fixed to the lower end of the interior of the furnace body; a heating device is fixed to the middle of the hopper-shaped shell; a baffle fixed in the furnace body is arranged at the upper end of the hopper-shaped shell; the baffle is arranged horizontally and provided with a plurality of through holes; a plurality of heating sheets are arranged on the inner wall of the furnace body; branch heating sheets arearranged on the side faces of the heating sheets; two temperature sensors are arranged on the inner wall of the furnace body; a smoke outlet A is formed in the upper end of the furnace body, and a net is arranged in the smoke outlet A; the upper end of the smoke outlet A is connected with a pipe A; and the other end of the pipe A is connected with a smoke inlet in the lower end of a steam tank. As the hopper-shaped shell in the furnace, heat is gathered, and the effect of saving is achieved; and the heating area is enlarged by arranging the herringbone heating sheets, heat is utilized for generating steam to generate power, heat can be recycled, and thus the energy saving and emission reduction effects are achieved.

Description

technical field [0001] The invention relates to the field of metal smelting, in particular to an energy-saving heating furnace. Background technique [0002] In recent years, with the prosperity of our country's economy, steel consumption and steel production have increased year by year, and the prices of raw materials for production of steel enterprises have continued to soar. In 2007, the world iron ore price and main coking coal price rose sharply. The soaring price of raw materials for steel production has resulted in a sharp drop in the profits of the steel industry, and the selling prices of some domestic products have approached the cost. Some ordinary steel companies with low added value of products are burdened by the mismatch between the soaring prices of raw materials and the sales prices of products, and it is even more difficult to move forward. Therefore, domestic iron and steel enterprises should implement converter negative energy steelmaking as soon as pos...

AI Technical Summary

Problems solved by technology

The current heating furnace loses a lot of heat when heating, and the heat lost with the smoke is extremely large, which consumes a lot of energy and also increases unnecessary economic expenditures. The problem needs to be solved urgently
