High Efficiency Solid Electric Regenerative Boiler

Abstract

The invention relates to an efficient solid electric thermal storage boiler which comprises a thermal storage body, an inner thermal insulating layer, a circulating fan, a low-temperature air circulating passage, a high-temperature air circulating passage, a heat exchanger and an outer thermal insulating layer. The inner thermal insulating layer constructed by fire-resistant thermal insulating bricks is disposed on the outer surface of the thermal storage body and the high-temperature air circulating passage, the heat energy in the thermal storage body can only flows into the heat exchanger through the high-temperature air circulating passage, high-temperature air enters the heat exchanger under the attraction force of the circulating fan and acts, low-temperature air formed by cooling returns to a first passage hole through the low-temperature air circulating passage, the low-temperature air absorbs heat in the passage hole and becomes the high-temperature air, and the high-temperature air enters the high-temperature air circulating passage through a second passage hole and acts. The efficient solid electric thermal storage boiler has the advantages that the condition for allowing the thermal storage temperature of the solid electric thermal storage boiler to exceed 800 DEG C is created, the thermal storage capability of the thermal storage body is at least doubled, the weight of the added thermal storage materials is reduced, the manufacturing cost of the electric thermal storage boiler is lowered, equipment space occupation is reduced, equipment thermal conversion efficiency is increased, and power cost is lowered.

Description

technical field [0001] The invention relates to a high-efficiency solid electric heat storage boiler, which can reduce the heat dissipation loss of the solid electric heat storage boiler and improve the heat energy utilization rate of the electric heat storage boiler. Background technique [0002] my country's smog weather is very serious. Installing solid electric heat storage boilers to use off-peak electricity and abandoning wind power for heat storage to replace coal-fired boilers is an effective way to clean the atmosphere and reduce smog weather. In recent years, some progress has been made in this area, but in practical applications, high-power, high-temperature output electric heat storage boilers with heat storage body temperatures above 800 degrees Celsius are required. The scheme will increase the heat loss of equipment heat preservation, reduce the heat conversion efficiency, and increase the cost of electric heat storage. Designing a new type of high-efficiency...
