Multi-branch type waste heat recovery cooker

Abstract

The invention relates to the technical field of gas boilers of main cooking equipment in kitchen matching, in particular to a multi-branch waste heat recovery type cooker. The multi-branch type wasteheat recovery cooker comprises a stove body, a first heat preservation water tank, a first water valve, a second heat preservation water tank, a second water valve, a smoke collection box, a third heat preservation water tank and a waste heat utilization system; and the stove body comprises a cooking bench, a groove, a through hole, a smoke exhaust hole, a burner and a support frame. According tothe multi-branch waste heat recovery type cooker, a multi-branch pipeline structure is used for regionally utilizing the residual heat of the flue gas after combustion of the fuel gas, and meanwhile,the multi-branch structure is divided, wherein one part of the water is heated to generate hot water, and the other part of the water is heated to generate high-temperature water vapor; and due to theadoption of the multi-branch structure, the flue gas subjected to heat exchange with the multi-branch structure continuously generates turbulence, so that the flue gas and the flue gas are fully mixed, and the multi-branch structure and the flue gas are subjected to high-efficiency heat exchange.

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 multi-branch type waste heat recovery boiler and stove. 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 flue gas after combustion of gas is generally to directly heat water or heat water to generate steam.

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. 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 flue gas after combustion of gas is generally to directly heat water or heat water to generate steam. This single utilization method fails to make full use of the waste heat.
