Vapor generator

Abstract

The invention discloses a vapor generator. The vapor generator comprises a generator body comprising a machine frame, a water tank and a combustor, wherein the water tank and the combustor are arranged in the machine frame, the water tank is connected with a water inlet pipe and a vapor outlet pipe and comprises a tank body and a tank cover connected to the tank body, the combustor is arranged corresponding to the tank body comprising a heating surface, the combustor is arranged towards the heating surface, the tank cover is provided with an upper hole, the heating surface is provided with a lower hole, a containing cavity in which a heating pipe is arranged is formed in the water tank, one end of the heating pipe plugs the upper hole, the other end of the heating pipe plugs the lower hole, and hot vapor channels communicated with one another are arranged in the heating pipe. The vapor generator has the advantage of being high in heat energy use ratio.

Description

technical field [0001] The invention relates to the technical field of kitchen utensils, more specifically, it relates to a steam generator. Background technique [0002] A steam generator is a mechanical device that uses fuel or other energy to heat water into steam. It can provide high-temperature steam for various steam-heated kitchen cooking equipment. It is widely used in steaming and stewing in the catering industry, such as: steaming vegetables, Steam rice, cook porridge, cook soy milk, stew soup. [0003] Steam generators are generally divided into two types of steam generators: electric heating and fuel heating according to their heating methods; most of the steam generators currently used in the field of kitchen utensils use liquefied gas or natural gas to heat water. Water is heated into steam. The advantages of this steam generator are fast heating speed and large steam output, which can provide steam to multiple equipments. The disadvantage is that the steam ou...

Problems solved by technology

[0005] Since the fuel ejected from the burner burns in the hollow heating inner tank, and when the inner wall of the heating inner tank is heated, the connecting pipe is still heated, thereby increasing the heating area to improve the utilization rate of heat energy; wherein, Most of the heat energy generated by fuel combustion is transferred to the connecting pipe, and transferred to the steam generating chamber through the heated inner tank; the remaining heat energy is dissipated into the air in the form of radiation, which makes the temperature of the air in the heated inner tank higher, and It rises rapidly into the smoke pipe, and then discharges into the air. Generally, the high-temperature air discharged has a high temperature, and the current steam generator cannot effectively use this part of heat energy, so the heat energy utilization rate of the current steam generator low; room for improvement
