Multifunctional waste heat recovery type cooking range

Abstract

The invention relates to the technical field of main cooking equipment gas boilers in kitchen supporting facilities, in particular to a multifunctional waste heat recovery type cooking range. The multifunctional waste heat recovery type cooking range comprises a cooking range body, a high-temperature steam box, an air conveying pipe I, a low-temperature steam box, a air conveying pipe II, a heat preservation water tank, a smoke guiding hood, a waste heat utilization system, a water drain pipe I, a water outlet pipe, a water inlet pipe I, a water inlet pipe II and a water drain pipe II. According to the cooking range, by utilizing the difference in quality between the water and steam, a water film formed between water and a spherical structure, the spherical structure and a pipe structure are used for separating the heat exchange areas through the spherical structure and a structure matched with the spherical structure; and the water and the heat exchange structures in different heat exchange areas are subjected to heat exchange with the steam in the process of heating water, and finally high-temperature steam and low-temperature steam are separated, so that high-temperature water vapor and low-temperature water vapor are more easily generated and fully utilized.

Description

technical field [0001] The invention relates to a gas-fired boiler, which is the main cooking equipment used in kitchen matching, and in particular relates to a multifunctional waste heat recovery type cooker. Background technique [0002] At present, the cooking gas cooker has become the main tool for cooking various dishes in the kitchen. Traditional cooking gas boilers consume a lot of energy and have low energy efficiency. They can’t even reach the basic 45% thermal efficiency index. Especially the blast stoves can meet the combustion firepower required for cooking and increase the heat load, but the energy efficiency is very low. If the thermal efficiency is only between 35% and 38%, more than 60% of the combustion heat energy will be wasted in vain through the flue. [0003] The traditional way of utilizing the waste heat of exhaust gas after combustion of gas is generally to heat water to obtain hot water or generate high-temperature steam to heat water. This single ...

The thermal efficiency is only between 35% and 38%, and more than 60% of the combustion heat energy is wasted in vain through the flue.

[0003] The traditional way of utilizing the waste heat of exhaust gas after combustion of gas is generally used to heat water to obtain hot water or generate high-temperature steam to heat water. This single utilization method fails to make full use of the waste heat
