Abstract

The utility model relates to a water heating stove for living. The utility model is characterized in that the water heating stove has an inner and an outer water layers, wherein the inner water layer is arranged outside a hearth chamber and the outer water layer is arranged outside the inner water layer. The inner water layer uses fuel to directly heat soft water which is treated (or steam condensate, or rain or snow water), so that steam can be generated and ordinary water in the outer water layer can be indirectly heated. Accordingly, the utility model has the advantages that the scale deposit is not generated, the heat efficiency is improved, the fuel is saved and the safe and reliable work is obtained. The utility model can be made into serial products with various specifications to satisfy the different requirements of communities in different scales.

Description

The Double-layer water heater

The utility model is a kind of life water heater.

At present, the used domestic hot-water stove of general group is single water layer water heater or high-pressure boiler.Single water layer water heater, no heat-insulation layer is heated up water, is just ceased fire after the steamed rice, and unspent hot water just slowly turns cold in the stove, wastes energy.Minority operator after hot water is used, is put into not bath in time under the waterline to water, and the thing that flue burns out is happened occasionally.Single water layer water heater flue incrustation scale gathers, and untimely cleaning causes the thermal efficiency to reduce, and energy loss is big.High-pressure boiler costs an arm and a leg, the operating cost height, and the user is uneconomical.

The purpose of this utility model is to provide a kind of heat insulation effect that has, without scale removal, keep the water heater of high efficiency, safety, fuel savings, operating cost economical rationality for a long time.

Structure of the present utility model as shown in Figure 1, the body of heater centre is a burner hearth 2, its underpart is a fire door 1, a horizontal flue 3 is arranged at top.The outside of burner hearth 2 is inner aqueous layers 7, and a steam (vapor) outlet 5 and a water inlet pipe 6 through to the bottom are arranged at its top.The outside of inner aqueous layer 7 is outer water layers 8, and there is hot water outlet 4 its middle and upper part, and cooling water inlet 9 is arranged at the bottom.Whole body of heater is fixed on the base 10 that brick and cement is built into.Soft water after treatment (or steam condensate (SC), sleet water) injects inner aqueous layers 7 from water inlet pipe 6.Light water is water layer 8 outside cooling water inlet 9 injects.After the water of inner aqueous layer 7 is boiled, can carry steam by steam (vapor) outlet 5, with the water heating of outer water layer 8, outwards provide hot water simultaneously by hot water outlet 4.The water that replenish to inner aqueous layer 7 are treated soft water or steam condensate (SC), sleet water.The waste heat of the high-temperature flue gas that flue 3 is discharged can further utilize.

Compare with existing single water layer water heater, the utility model has following advantage: 1,8 pairs of inner aqueous layers 7 of outer water layer have insulation effect, when refire time heats up, but fuel saving; 2, the water level in the inner aqueous layer 7 is higher all the time, safety, easy burn-out not; 3, inner aqueous layer 7 is difficult for producing incrustation scale, thermal efficiency height, fuel savings; 4, reasonable price, user's operating cost economy.

Accompanying drawing 1 is a schematic diagram of the present utility model.

The utility model can be made into different specifications, forms series of products, satisfies user's different needs.With 1 ton of capacity is example, appearance and size 1000mm * 2200mm (external diameter * highly), inner aqueous layer 7 diameter 800mm, burner hearth 2 diameter 700mm, high 1200mm, fire door 1 sectional dimension 200mm * 300mm (high * wide), flue diameter 50mm, hot water outlet 4 diameter 25mm, steam (vapor) outlet 5 diameter 80mm, water inlet pipe 6 diameter 25mm, cooling water inlet 9 diameter 25mn.Outside the deaeration water entrance, all aluminium alloy or stainless steel materials are made.

Claims

1. a Double-layer water heater is made up of burner hearth, body of heater, turnover carbonated drink pipe, it is characterized in that the body of heater centre is burner hearth (2), and there is a fire door (1) its underpart, and a horizontal flue (3) is arranged at top; The outside of burner hearth (2) is that a steam (vapor) outlet (5) and a water inlet pipe through to the bottom (6) are arranged at its top of inner aqueous layer (7); The outside of inner aqueous layer (7) is outer water layer (8), and there is hot water outlet (4) its middle and upper part, and cooling water inlet (9) is arranged at the bottom.
