Abstract

The invention provides a heat accumulating type heat preservation boiler, and belongs to the technical field of heat preservation equipment. The heat preservation boiler comprises a hearth, and a chimney communicating with the interior of the hearth is arranged at the top of the hearth; a fire grate is arranged at the lower part in the hearth, the hearth comprises an outer protection layer, a heat preservation layer and a refractory brick layer from outside to inside, and heat accumulating bricks are arranged inside the hearth; and the heat preservation boiler further comprises a temperature monitoring system, and the temperature monitoring system is composed of a temperature controller, an alarm device and a temperature sensor. The heat accumulating bricks are obtained by mixing, forming, drying and sintering 25-30% of high alumina, 20-25% of aluminium silicate, 15-20% of zirconium silicate, 6-10% of high-purity magnesia, 8-11% of silicon nitride, 2-3% of titanium dioxide, 6-10% of silica sol and 4-6% of water by weight percentage. The heat accumulating type heat preservation boiler has the advantages that the structure is simple, the heat preservation effect is good, the thermal efficiency is high, heat supply is stable and uniform, the use durability is good, and the controllability is high.

Description

【Technical field】 [0001] The invention relates to the technical field of heat preservation equipment, in particular to a heat storage type heat preservation boiler. 【Background technique】 [0002] With the development of the economy, energy shortage and environmental issues have become the focus of global attention, and energy conservation and environmental protection have attracted more and more attention. Boiler is a kind of energy conversion equipment. It releases chemical energy through coal, oil, natural gas and other fuels, transfers energy to water or other heat transfer medium through heat transfer process, and directly supplies various products required in industrial production in the form of steam or heat transfer medium. forms of energy. It involves the process of energy conversion, storage and transportation, and the use of energy-saving technologies in each link is of great significance to energy conservation and environmental protection. [0003] Heat storage...
