Energy-saving-type boiler

Abstract

The invention discloses an energy-saving-type boiler. The energy-saving-type boiler comprises a furnace body, wherein the furnace body comprises a furnace wall; the furnace wall comprises an inner layer and an outer layer; a heat insulation layer is arranged in a clearance between the inner layer and the outer layer; four support legs which are uniformly distributed are arranged on the bottom of the furnace body; a pressure valve and a steam pipe are arranged on the top of the furnace body; a water tank and a smoke exhaust pipe are arranged on one side surface of the furnace body; a water inlet pipe is arranged on the bottom of the water tank; heat exchange sheets are arranged in the smoke exhaust pipe; a radiation plate is arranged in the water tank; radiation fins which are uniformly distributed are arranged on the radiation plate; a heat conduction sheet is arranged between the heat exchange sheets and the radiation plate; and the side surface, which is close to the water tank, of the furnace body is provided with a thermometer, a pressure gage and a material inlet. By adopting the energy-saving-type boiler, heat in the smoke exhaust pipe can be absorbed and utilized again; an energy-saving effect can be realized; the heat conversion efficiency of the boiler is improved; the use effect is better; the use amount of fuel coal is reduced; and economic benefit of an enterprise is improved.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to an energy-saving boiler. Background technique [0002] Since my country's reform and opening up, the national economy has grown rapidly, and "scientific and technological innovation, independent innovation" has become the mainstream of my country's current industrial development. At the same time, my country's industry is also developing in the direction of intensive, energy-saving, emission-reducing, and low-carbon. Traditional coal-fired boilers are large energy consumers and one of the root causes of environmental pollution. In order to meet the requirements of urban environmental development and improve the economic efficiency of enterprises, more and more enterprises have quietly joined the ranks of clean energy alternatives. Biomass boiler is a boiler with biomass energy as fuel, which is a new type of energy boiler. On the one hand, biomass boilers can reduce SO emissions...

AI Technical Summary

Problems solved by technology

When the biomass boiler burns straw fuel, a large amount of heat is discharged from the boiler with the exhaust pipe, which reduces the thermal energy conversion efficiency of the boiler and affects the effect of the device.
