Abstract
The utility model relates to a fire tube type normal-pressure energy-saving gas-burning steam boiler, which belongs to the field of heating and cooking range. The utility model is composed of an outer shell, a water holding dish, a gas burner, a fume pipe and a fire tube, wherein the lower part of the water holding dish is provided with the fire tube which is connected with the gas burner; the gas burner is arranged at the bottom of the water holding dish; the fume pipe is connected with the fire pipe, and an extractor is arranged on the fume pipe; the zigzag fire pipe has two layers or more. The utility model has reasonable structure design, high heat efficiency utilizing rate, small volume, favorable heat absorption, lower use cost and large heat load, and is a fire tube type normal-pressure energy-saving gas-burning steam boiler with environmental protection and energy saving.
Description
The utility model fire-tube type atmospheric energy-saving combustion gas steam stove belongs to heat supply, cooking stove field, particularly a kind of equipment that utilizes the steam processed food.
Existing steam stove is to adopt combustion gas heating water generates steam, in the bottom of water dish gas burner is installed, and the heat that makes water dish absorb is limited, at the bottom of the heat absorption efficient, causes the waste of combustion gas, the use cost height.
The purpose of this utility model is to avoid the deficiencies in the prior art part and a kind of thermal efficiency utilization rate height is provided, and volume is little, and it is good to absorb heat, and use cost is low, and thermic load is big, the fire-tube type atmospheric energy-saving combustion gas steam stove of environmental protection and energy saving.
The purpose of this utility model reaches by following measure, it is by shell, water dish, gas burner, smoke exhaust pipe, fire tube is formed, and is used for putting the cabinet of food container on the top of water dish, bottom at water dish is provided with fire tube, fire tube links to each other with gas burner, and gas burner is arranged on the bottom of water dish, and smoke exhaust pipe connects fire tube, smoke exhaust pipe is provided with air exhauster, fire tube be two-layer or two-layer more than, fire tube adopts in a zigzag, gas burner is when burning, the flame of high temperature and flue gas enter the upper strata fire tube by the fire tube inlet of centre, be diffused into the edge by the centre, flame and flue gas move towards lower floor's fire tube by the upper strata fire tube, discharge from smoke exhaust pipe, owing to adopt fire tube, heat transfer area is enlarged, and the heating surface area of water dish increases, and is surrounded by water around upper strata fire tube and the lower floor's fire tube, the heat that gas burner produces is absorbed thermal efficiency utilization rate height by water.
Fire tube of the present utility model be two-layer or two-layer more than, fire tube adopts in a zigzag.
The utility model reasonable in design, thermal efficiency utilization rate height, volume is little, and it is good to absorb heat, and use cost is low, and thermic load is big, is a kind of fire-tube type atmospheric energy-saving combustion gas steam stove of environmental protection and energy saving.
Accompanying drawing 1 is an example structure schematic diagram of the present utility model.
Accompanying drawing 2 is A-A cut-away views of accompanying drawing 1.
The utility model is described in further detail below in conjunction with accompanying drawing.
As accompanying drawing 1, shown in the accompanying drawing 2, the utility model is by shell 6, water dish 4, gas burner 2, smoke exhaust pipe 7, fire tube 3, air exhauster 1 is formed, be used for putting the cabinet of food container on the top of water dish, water channel is arranged in water dish, be provided with fire tube in the bottom of water dish, fire tube is two-layer about being divided into, bottom at fire tube is provided with gas burner, smoke exhaust pipe connects fire tube, and smoke exhaust pipe is provided with air exhauster, and fire tube adopts in a zigzag, gas burner is when burning, the flame of high temperature and flue gas enter the upper strata fire tube by the fire tube inlet of centre, leave about being divided into, and are diffused into the edge by the centre, flame and flue gas move towards lower floor's fire tube by the upper strata fire tube, discharge from smoke exhaust pipe.
As shown in Figure 3, fire tube of the present utility model is to adopt in a zigzag, and the flame of high temperature and flue gas are turned round in fire tube, has increased heating surface area and the flame of high temperature and the heat exchanger time of flue gas of water.
