Description

A kind of efficient energy-saving coal-firing stove

The utility model relates to a kind of pyrogenetic water heater that has, and is specially a kind of efficient energy-saving coal-firing stove.

The Coal stove for making tea that is commonly used at present is to be built-in with the transversely arranged heating tubulation that is connected with water cavity at its burner hearth.This coal furnace heat transfer area is little, and the thermal efficiency is low, and it is slow to heat up, and energy-saving effect is not good.

The utility model purpose provides a kind of efficient energy-saving coal-firing stove, this coal furnace thermal efficiency height, and heat-transfer capability is big, quick heating, good energy-conserving effect.

To achieve these goals, the utility model be the water cavity that the inner housing by the shell body of stove and stove constitutes be built-in with its bottom place burner hearth in the U type Super-conductive conduit tubulation of heat-conduction medium is housed, burner hearth be built-in with that its two ends that number row arranges side by side are fixed on the inner housing and and the convection tube that is connected of water cavity, in burner hearth in being equipped with between the two rows convection tube by the inner lining body that is equipped with on the inner housing that is fixed in stove, inner lining body is built-in with the interior water cavity that is connected with water cavity, is equipped with the hot-water heater that is built-in with Super-conductive conduit that places outside the body of heater on the top of body of heater.

The Super-conductive conduit that U type Super-conductive conduit that the utility model institute furnace chamber is equipped with and hot-water heater are built-in with vacuumizes rear enclosed at the adding heat-conduction medium.Because the utility model is equipped with U type Super-conductive conduit tubulation, convection tube and inner lining body, the heat that produces during coal combustion in the burner hearth not only can heat the water in the water cavity by the stove inner housing, but also by U type Super-conductive conduit, convection tube, inner lining body heats water, make it the very fast intensification of water, and generation water vapour, to satisfy the heating demand, be equipped with hot-water heater simultaneously, Super-conductive conduit in the heater by the water heat temperature raising in the water cavity after heat pass to water in the hot-water heater again, make it heater for the usefulness of hot water is provided specially, and the providing of water vapour of this stove is not provided.The utility model area of heat transfer is big, quick heating, thermal efficiency height, hot water is provided and provides steam to be independent of each other, energy-saving effect is remarkable, can provide hot water and a large amount of water vapours to be applied to the large tracts of land heating, be that a kind of a large amount of steam are provided is main application and the comparatively desirable coal furnace that hot water can be provided with heating.

Below in conjunction with accompanying drawing the utility model is explained
