Abstract

The utility model relates to an energy-saving industrial furnace which comprises a fuel jet tube, a combustion chamber and a hot water chamber from bottom to top, wherein the height of the upper portion of the combustion chamber is 40-60% of the height of the whole combustion chamber, pre-heating water grooves are fixed on the lower portion of the combustion chamber and the external surface of the hot water chamber, the pre-heating water grooves surround the lower portion of the combustion chamber and the external surface of the hot water chamber, a multiple layers of spiral flue tubes are arranged in the hot water chamber, the lower port of the flue tube is communicated with the upper portion of the combustion chamber, the upper port of the flue tube extends outside the hot water chamber and is connected with a discharge fan, a residual heat utilizing groove is fixed on the flue tube outside the hot water chamber, fuel is sprayed into the combustion chamber through the jet tube, after burns in the combustion chamber, is discharged through the flue tube by the discharge fan, cold water is firstly heated in the lower portion of the combustion chamber and the external surface of the hot water chamber, then enters into the hot water chamber, and is heated by the flue tube in the hot water chamber, the residual heat in the tail section of the flue tube is further absorbed by the cold water in the residual heat utilizing groove, heat is fully utilized during the whole process, and the energy saving effect is obvious.

Description

The energy-saving industrial boiler

Technical field

The utility model relates to Industrial Boiler, promptly a kind of Remarkable Energy Saving Industrial Boiler.

Background technology

Present boiler, burn coal, that burn combustion gas, or oil firing no matter be, the mode of heat exchange is single, only on the top of combustion chamber, the area of heat exchange is little, and a large amount of heat energy distributes to air from the wall and the walling of flue of combustion chamber, causes a large amount of heat-energy losses, make the fuel consumption height, hot water and steam that boiler produces are few.

Summary of the invention

The shortcoming little in order to overcome present boiler heating surface, that a large amount of heats scatter and disappear the utility model proposes a kind of new design that makes full use of the boiler of combustion chamber and flue heat energy.

This energy-saving industrial boiler, comprise fuel nozzle from bottom to up, combustion chamber and hot hydroecium, Pressure gauge is arranged in the hot hydroecium, safety valve and steam pipe, it is characterized in that, the top of combustion chamber, be 40～60% of whole combustion chamber height, be deep in the hot hydroecium, be fixed with the preheating tank at the outer surface of bottom, combustion chamber and hot hydroecium, the preheating water grooved ring is around bottom, combustion chamber and hot hydroecium's outer surface, several layers is arranged, adjacent two-layer head and the tail up and down communicate, and the water inlet of cold water pipe and preheating tank lower floor communicates, and the preheating tank circulates upwards gradually, the terminal delivery port and the hot hydroecium of the superiors communicate, the smoke pipe that in hot hydroecium, has several layers to spiral, smoke pipe end opening and top, combustion chamber communicate, and suitable for reading the stretching out outside the hot hydroecium of smoke pipe also links to each other with air exhauster, on the smoke pipe outside hot hydroecium, be fixed with the UTILIZATION OF VESIDUAL HEAT IN groove, the UTILIZATION OF VESIDUAL HEAT IN groove is a helically coiled, is wrapped on the smoke pipe, the water inlet of one end of cold water pipe and UTILIZATION OF VESIDUAL HEAT IN groove communicates, and the delivery port and the hot hydroecium of the other end of UTILIZATION OF VESIDUAL HEAT IN groove communicate.

Fuel sprays into the combustion chamber by jet pipe, after combustion chambers burn, discharge by air exhauster through smoke pipe, cold water is preheating in the preheating tank of bottom, combustion chamber and hot hydroecium's outer surface at first, enter hot hydroecium then, be subjected to the heating of smoke pipe in hot hydroecium, the waste heat of smoke pipe latter end is absorbed by the cold water in the UTILIZATION OF VESIDUAL HEAT IN groove again, whole process heat is utilized fully, and energy-saving effect is remarkable.
