Problems solved by technology

[0005] 1. The flame of fuel combustion only undergoes a process of exothermic utilization, so that the goal of completely clean combustion cannot be achieved in one combustion, and the smoke at the end of the flame smoke flow is discharged into the atmosphere, wasting energy and polluting the environment
[0006] 2. The cylindrical combustion chamber structure leads to the axial flow of the flame and smoke flow, and the heating surface of the water jacket can only accept the radiant heat of the outer ring of the rapidly flowing flame and smoke flow, while the strong high-temperature direct heat in the middle part It flows to the front low temperature area, so the part of the heat that is too late for heat exchange is discharged from the chimney. In order to reduce heat loss, the only way to increase the heating area of ​​the water jacket and heat exchanger or the auxiliary waste heat utilization device is to increase the volume of the boiler and increase the cost. and production difficulty
In fact, it is a utilization process of flame combustion, and there is no reliable condition to make the combustible gas completely clean and burn to ashes

Abstract

The present invention provides efficiency raising heat exchanging method and temperature raising hood for water heating boiler and the water heating boiler. Inside the furnace body, there are several transverse heat utilizing high temperature zones and low temperature zones to collect flame end and fume flow end of the hearth, the outer combustor cavity or the outer combustor cavity for secondary or multiple gas supply. Under the control of the temprature raising hood, re-mixing combustion and multiple transverse heat utilization are reached. The present invention makes it possible to burn the combustible gas fully and utilize heat effectively and has the features of high heat exchange efficiency, good environment protecting performance, no black smoke exhausted, no dust exhausted, etc.

Description

[0001] Field: [0002] The invention designs an efficiency-enhancing heat exchange method and a warming cover for a hot water boiler. Background technique: [0003] In existing boilers, most of the combustion chambers surrounded by water jackets have a cylindrical structure. This structure forms a combustion method with low efficiency of flame combustion and heat release. Especially for small boilers, this combustion method has high exhaust gas temperature and high thermal efficiency. Low, and the problem of smoke and dust emissions not meeting the standards is particularly prominent. [0004] The inefficient use of this combustion method is mainly manifested in the following two aspects: [0005] 1. The flame of fuel combustion only undergoes a process of exothermic utilization, so that the goal of completely clean combustion cannot be achieved in one combustion, and the flue gas at the end of the flame flue gas flow is discharged into the atmosphere, wasting energy and poll...
