Abstract

The utility model relates to a multipurpose hot water boiler with high efficiency and energy saving. A boiler body is divided into a boiler hearth, a burning out chamber and a heat exchange chamber. The heat exchange chamber adopts a water jacket with a wavy plate type structure. The slit of the water jacket forms an S shape. The flow speed of the smoke gas is accelerated, the heat exchange area is enlarged, the heat exchange coefficient is high, and the utility model is suitable for various hot water boilers.

Description

The efficient power-saving multiple-purpose hot-water boiler

The utility model belongs to the fluid heater that heat-generating device is arranged, and is specifically related to a kind of efficient power-saving multiple-purpose hot-water boiler.

In the known technology, hot-water boiler adopts the comb heat exchange usually, and its thermal efficiency is lower, easy dust stratification between the pipe.CN2034666, CN2143308 disclose the boiler heat exchanging water-jacket of a class plank frame, and it only is arranged on " boiler both sides ".Or " board-like all around water-cooling wall ", this class formation fails to make full use of the hot environment at body of heater center, and the heat exchange effect is subjected to certain limitation.

It is high that the purpose of this utility model is to provide a kind of heat to imitate, the multi-purpose hot water boiler structure that energy consumption is low.

The utility model is taked following technical scheme.

The efficient power-saving multiple-purpose hot-water boiler includes body of heater, burner hearth, thin water jacket, firebrick lining, in the body of heater vertically every being divided into burner hearth, burning chamber, Heat Room.Heat Room is provided with wave mode plank frame water jacket, and the setting of water jacket is two S shapes with water jacket plate slit and arranges that water jacket plate inner chamber is communicated with furnace water jacket.Around arranging thin water jacket, be lined with refractory material along inboard wall of furnace body outward.In order further to increase heat exchange effect, the uniform fin that is provided with of wave mode plank frame water jacket outer surface.

The utility model operation principle is such.

Owing to take three Room every branch, make fired coal combustion more abundant, be suitable for the coal expanded range, coal-fired after the burner hearth internal combustion, flue gas flows into burning chamber, carbon granules that flue gas further will not burn and the full combustion of gas that does not burn in burning chamber.The hot flue gas that burns flows into Heat Room, and flue gas flows through the undaform plank frame water jacket of being with fin with two S types, has improved the coefficient of heat transfer greatly.

The utility model has significant technique effect compared to existing technology.Flue gas and medium (water) flow velocity strengthens, and changes (biography) heat and strengthens.The water jacket of the board-like band fin of undaform has increased the heat exchange heating surface, and flue gas is when flowing through the boundary layer, because of the raising coefficient of heat transfer is moved in disturbance more.The utility model is compared the prior art effect comparison and is seen attached list.
