Abstract
The utility model relates to a thermal efficiency monitoring device for a boiler, which is characterized in that the output of a sensing detection device is connected with the input of a controller which is connected with a display, the output of the controller is connected with a blower driving amplification and execution device, and the sensing detection device arranged in a leading tube of a connecting smoke flue comprises a sampler, a zirconia sensor and a smoke detection sensor. The utility model has the advantages of measuring the thermal efficiency of the boiler conveniently and swiftly by utilizing a detector, a display controller and other devices, facilitating the operation, visualizing the thermal efficiency and other operational parameters of the boiler, achieving the automatic control of thermal efficiency, increasing the operating quality of the boiler and having obvious energy-saving effect.
Description
The utility model relates to a kind of boiler thermal output supervising device, is applicable to the automatic device of measuring and controlling boiler thermal output of boiler of various fuel burnings.
At present, the way that detects boiler thermal output be by full-time heat energy monitoring department by the multinomial data of on-the-spot test, computation of table lookup draws the multiple parameters value again, at last by positive balance or anti-EQUILIBRIUM CALCULATION FOR PROCESS, just can draw the thermal efficiency of filtration, the process more complicated is not easy to know boiler operatiopn.
The purpose of this utility model is to provide a kind of boiler thermal output supervising device at the deficiency of prior art, can test and control the thermal efficiency of boiler automatically, makes boiler reach the optimal combustion state of automatic maintenance high efficiency boiler rate, saves the energy.
The purpose of this utility model is achieved in that a kind of boiler thermal output supervising device, its sensing detection device output connects the input of controller, controller is connected with display, and controller output is connected to blower fan and drives amplification executing agency, and sensing detection device is arranged in the flue of boiler.
Sensing detection device is arranged in the air entraining pipe, and air entraining pipe connects flue.
Sensing detection device comprises sampler, zirconia sensor, survey smoke sensor.
According to the technique scheme analysis as can be known, the utility model utilizes detector, demonstration controller etc. to measure the thermal efficiency of boiler quickly and easily, bring convenience to operation, and can see the operational factors such as the thermal efficiency of boiler intuitively, realize the automatic control of the thermal efficiency, improve the boiler operatiopn quality, energy-saving effect is obvious.
Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.
Fig. 1 installs for the utility model and constitutes schematic diagram;
Fig. 2 is the utility model circuit theory diagrams.
Referring to Fig. 1, the utility model is a kind of boiler thermal output supervising device, and the sensing detection device 2 that it comprises, controller 3 and blower fan 6 drive and amplify executing agency 5.The sensor of sensing detection device 2 etc. is arranged in the air entraining pipe 4, air entraining pipe 4 connects flue 1, the sensor of sensing detection device 2 comprises sampler, is provided with the zirconia sensor of thermal resistance or thermocouple and (adopts existing product, therefore portion describes its structure again in detail and forms), and be wrapped on the zirconia sensor, have a survey smoke sensor that the heating furnace etc. of temperature sensor is formed.Sensing detection device output connects the input of controller, and controller is connected with display, and the controller output machine of giving a dinner for a visitor from afar drives and amplifies executing agency.
As shown in Figure 2, after controller of the present utility model is finished analog-to-digital conversion by the input signal acquisition process circuit 0809 of each sensor, connect the input port line of CPU8031, CPU connects display and operation keyboard by keyboard display chip 8279, display can show the boiler operatiopn state in real time, and keyboard can be finished the work that is provided with adjustment.Wherein CPU is according to each transducing signal of sensing detection device transmission, and according to oxygen content, flue-gas temperature, carbon dioxide content in the flue gas of measuring, computational analysis draws excess air coefficient, the boiler thermal output in the flue gas.CPU also drives amplifying circuit triode T1, regulating circuit 3140 by the air door that output digital-to-analogue conversion chip 0832 connects as executing agency, so that change the unlatching size of air door, control boiler intake keeps the preferred fuel air ratio, realizes that boiler moves under the high thermal efficiency operating mode.
