Description
Technical field
The utility model relates to a kind of hot water boiler system.Belong to heating equipment technical field.
Background technology
It is fuel that normal-pressure hot-water boiler be take diesel oil or natural gas, by burner, water is heated, and realizes for warming up life, bathing hot water are provided.Normal-pressure hot-water boiler top is provided with atmosphere entry, and boiler body is all the time in normal pressure running status, and its main feature is exactly not pressure-bearing of boiler body, there is no potential safety hazard.This kind of boiler do not belong to special equipment, and design, production, installation and use are not subject to the supervision of technical supervision department.
In tradition oil-burning gas-fired boiler, due to reasons such as flue gas resistance, cold end corrosions, exhaust gas temperature design is all higher than 150 ℃, the boiler of tail heating surface is not even higher than 250 ℃, in flue gas, water vapour, in superheated steam state, can not condense into aqueous water and emit the latent heat of vaporization, therefore, China is the same with other countries, adopts the low heat value of fuel as calculating benchmark in boiler thermodynamic calculation.If exhaust gas temperature can be dropped to enough lowly, the water vapour that is superheat state in flue gas will condense into aqueous water and emit the latent heat of vaporization.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of hot water boiler system that can further improve boiler thermal output is provided.
The purpose of this utility model is achieved in that a kind of condensing type highly effective normal-pressure hot-water boiler system, comprise boiler body, at described boiler body top, be provided with the first condenser and the second condenser, boiler body, the first condenser and the second condenser are connected in series successively by flue, the backwater of system enters the first condenser and the second condenser from a water collector outlet minute two-way parallel connection, boiler body water inlet, the first condenser delivery port and the second condenser delivery port junction top arrange expansion tank, the first condenser delivery port and the second condenser delivery port access expansion tank, boiler body water inlet is connected with expansion tank, boiler body water outlet is connected with circulating pump, circulating pump is connected with water knockout drum, expansion tank is connected with small pump, small pump is connected with softening water tank.
Compared with prior art, the utlity model has following advantage:
1, normal-pressure boiler increase utilizes the waste heat of boiler tail flue gas and the water vapour condensation heat release in flue gas, and boiler thermal output can reach more than 96%, and the normal-pressure boiler thermal efficiency of comparing frozen-free device improves more than 4%.
2, backwater parallel connection enters the first condenser, the second condenser, reduces water collateral resistance, guarantees the circulation of boiler lower resistance.
3, expansion tank is established on boiler feed water mouth top, and when water consumption is uprushed, moisturizing in time enters boiler, prevents that boiler water level decline from causing dry combustion method.
Accompanying drawing explanation
Fig. 1 is the heat flow diagrams of the utility model condensing type highly effective normal-pressure hot-water boiler system.
Reference numeral in figure:
The specific embodiment
Referring to Fig. 1, Fig. 1 is the heat flow diagrams of the utility model condensing type highly effective normal-pressure hot-water boiler system.As seen from Figure 1, the utility model condensing type highly effective normal-pressure hot-water boiler system, comprise boiler body 1, the first condenser 2, the second condenser 3, expansion tank 4, water collector 5, circulating pump 6, water knockout drum 7, small pump 8 and softening water tank 9, the first condenser 2 and the second condenser 3 are arranged on boiler body 1 top, boiler body 1, the first condenser 2 and the second condenser 3 are connected in series successively by flue, the backwater of system enters the first condenser 2 and the second condenser 3 from water collector 5 outlet minute two-way parallel connections, boiler body 1 water inlet, the first condenser 2 delivery ports and the second condenser 3 delivery port junction tops arrange expansion tank 4, after being collected by the water after the first condenser 2 and the second condenser 3 heating, enter boiler body 1, in the interior further heating of boiler body 1, reach predetermined leaving water temperature.Boiler body 1 water outlet is pumped to water knockout drum 7 by circulating pump 6, and by water knockout drum, 7 couples of users supply water.The moisturizing of system is that qualified demineralized water is admitted to softening water tank 9, by small pump 8, squeezes into the high-order expansion tank 4 of arranging.
Flue gas flow is:
The flue gas that burning produces passes through boiler body 1 successively, flue-gas temperature drops to 120 ℃ of left and right and enters the first condenser 2 and the second condenser 3,50 ℃ of the inflow temperatures of take are example, and temperature is further reduced to water vapour dew-point temperature in flue gas (70 ℃ of left and right) and enters atmosphere after following.
Water flow-path is:
The backwater of system divides two-way parallel connection to enter the first condenser 2, the second condenser 3 from water collector 5 delivery ports, after the water after the device that is condensed heating collects, enters boiler body 1, in the interior further heating of boiler body 1, reaches predetermined leaving water temperature.The expansion tank 4 of upper boiler is connected with boiler body 1 water inlet.While guaranteeing that hot water demand's amount is uprushed, when backwater has little time to enter boiler, the moisturizing in time of the water in expansion tank enters boiler, prevents that boiler water level decline from causing dry combustion method.
The moisturizing of system is that qualified demineralized water is admitted to softening water tank 9, by small pump 8, squeezes into the high-order expansion tank 4 of arranging.
