Abstract

The utility model discloses a gas heating water heater for controlling exhaust gas temperature, which comprises a combustor, a heat exchanger, a smoke exhaust pipe and a central controller, wherein the combustor is controlled by a proportional valve. Besides, a temperature sensor is installed at the position of the smoke exhaust pipe, temperature signals are transmitted to the central controller, and the central controller is used for controlling opening of a gas proportional valve according to the temperature signals. The gas heating water heater is capable of controlling the exhaust gas temperature higher than 110 DEG C, preventing the heat exchanger portion from producing condensed water, avoiding corrosion of the heat exchanger, simultaneously controlling the exhaust gas temperature lower than 125 DEG C and decreasing heat waste.

Description

The gas heater of water for heating of control exhaust gas temperature
Technical field
The utility model relates to gas heater of water for heating.
Background technology
At present, the common use of gas heater of water for heating, it is made up of the parts such as burner, heat exchanger, smoke exhaust pipe and central controller of gas ratio valve control.The flare size of this gas-heating burner mainly is to measure automatic control according to the indoor temperature of setting or with the hot water effluent.In the use, find following not enough: when exhaust gas temperature was lower than 110 ℃, the heat exchanger position can produce condensed water.Because condensed water can dissolve the portion C O in the flue gas X, N X, S XGas, formation has more highly acid corrosive liquid, can cause the heat exchanger heavy corrosion.State Standard of the People's Republic of China GB6932-2001 " domestic gas instantaneous water heater " explicitly calls for for the 1st section of the 6th article: exhaust gas temperature is controlled between 110 ℃~260 ℃.Because of exhaust gas temperature is high more, its heat that is discharged in the atmosphere is high more, causes the waste of fuel gas calorie, and the thermal efficiency is low, is not more than 260 ℃ so general water heater all is the control exhaust gas temperature, and has ignored the deficiency of bringing when being lower than 110 ℃.And exhaust gas temperature also causes damage to heat after 125 ℃.
Summary of the invention
The purpose of this utility model is to provide a kind of gas heater of water for heating that exhaust gas temperature can be controlled between 120 ± 5 ℃.
For achieving the above object, the technical scheme that its technical problem that solves the utility model adopts is: it comprises by the burner of proportional valve control, heat exchanger, smoke exhaust pipe and central controller, it is characterized in that, the place is equipped with temperature sensor at smoke exhaust pipe, temperature signal is transferred to central controller, central controller is according to the aperture of temperature signal control gas ratio valve, thereby adjust the combustion gas inlet of burner, to increase or to reduce exhaust gas temperature, exhaust gas temperature is controlled in 120 ± 5 ℃ of scopes.
The beneficial effects of the utility model are that the control exhaust gas temperature is higher than 110 ℃, makes the heat exchanger position not produce condensed water, has avoided the corrosion of heat exchanger.Control exhaust gas temperature simultaneously and be lower than 125 ℃, reduced heat waste.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a structural map of the present utility model.
Marginal data: 1---smoke exhaust pipe; 2---temperature sensor; 3---central controller; 4---gas ratio valve; 5---burner; 6---heat exchanger.
The specific embodiment
With reference to accompanying drawing structure of the present utility model is further specified.
As shown in Figure 1, it comprises existing burner 5, heat exchanger 6, smoke exhaust pipe 1 and central controller 3 by gas ratio valve 4 controls, 1 place is equipped with temperature sensor 2 at smoke exhaust pipe, temperature signal is transferred to central controller 3, central controller 3 is according to the aperture of temperature signal control gas ratio valve 4, thereby adjust burner 5 the combustion gas inlet, to increase or to reduce exhaust gas temperature, exhaust gas temperature is controlled in 120 ± 5 ℃ of scopes.
Temp probe 2 and gas ratio valve 4 all are connected with central controller 3 in Fig. 1, and the control electric current by central controller 3 control gas ratio valves 4 makes gas ratio valve 4 reach suitable aperture.When exhaust gas temperature during greater than 120 ℃, the combustion gas air inflow reduces, and exhaust gas temperature reduces gradually; When temperature sensor 1 detects exhaust gas temperature less than 115 ℃, central controller 2 increases the control electric current of gas ratio valve 4, and gas ratio valve 4 apertures increase, and the combustion gas air inflow increases, exhaust gas temperature increases gradually, thereby makes exhaust gas temperature be controlled at 120 ± 5 ℃ of scopes all the time.
