Abstract
The utility model discloses an online detecting combustion efficiency analyzer. The utility model herein comprises an oxygen probe, a temperature probe, an air-opening temperature probe, and a processor, wherein the oxygen probe and the temperature probe are in serial connection and are in electric connection to one port of the processor; wherein the air-opening temperature probe is in electric connection to another port of the processor; wherein the port where the oxygen probe and the processor are connected can be in electric connection to a CO probe. The oxygen probe herein is characterized by long service lifetime and free of smoke and air flow effect from flue and can work long time under high temperature, which permits small work load and low operation cost and provides quantitative data for management staff to increase high working efficiency of the boiler. The CO probe in the utility model can give immediate detection of reducing condition in combustion phase.
Description
Technical field
The utility model relates to a kind of instrument, specifically refers to a kind of online analyser that detects burning efficiency.
Background technology
When the burning efficiency of needs detection boiler, by detecting with hand-held instrument, this quasi-instrument is because easy to carry often for the technician, and degree of accuracy is higher, so use comparatively extensive.The principle of instrument is extracted the tail gas of boiler out for using aspiration pump, tail gas is sent into carried out electrochemical analysis and calculating in the instrument then, and the data presentation that goes out through technology is come out like this.Also just because of the degree of accuracy height, so this instrument is comparatively expensive; And the draft of aspiration pump can't reach the requirement of extracting gases sometimes for the higher flue gas of flow velocity at all, thereby thereby can not carry out on-line continuous and measure inconvenient boiler management personal management; Because the use of instrument needs stronger professional ability, and therebetween the electrochemical sensor life-span short, be that people want the technical matters that solves but how a kind of instrument economical and practical, on-line measurement easy to use is provided always.
The utility model content
The purpose of this utility model provide a kind of can online detection burning efficiency, make things convenient for the online analyser that detects burning efficiency of boiler management personal management, and economical and practical, easy to use, current energy-saving and emission-reduction are also had crucial meaning.
The technical scheme that its technical matters that solves the utility model adopts is; Online detection combustion efficiency tester comprises oxygen measuring probe, temperature probe, survey draught temperature probe, processor; Described oxygen measuring probe, temperature probe parallel connection are electrically connected with a port of processor, and described survey draught temperature probe is electrically connected with another port of processor.
The port that described oxygen measuring probe is connected with processor also can be electrically connected one and survey the CO probe.
The beneficial effects of the utility model are, owing to selected long-life influence and oxygen measuring probe that can under long term high temperature, work that is not subjected to flue gas stream for use, the system maintenance work amount is little like this, use cost is low, and the boiler operatiopn managerial personnel is improved boiler operating efficiency effectively quantitative data is provided; Owing to increased the CO probe, the effect that detects is immediately played in oxygen debt burning again for combustion phases so in addition.
Description of drawings
Fig. 1 is that the utility model is in the user mode simplified schematic diagram;
Fig. 2 is a fundamental diagram of the present utility model;
1. oxygen measuring probes among the figure are 2. surveyed the CO probe, and 3. temperature probe is 4. surveyed the draught temperature probe, 5. combustor, 6. boiler, 7. chimney, 8. processor.
Embodiment
As shown in Figure 1, the utility model comprises oxygen measuring probe 1, temperature probe 3, surveys draught temperature probe 4, processor 8; Described oxygen measuring probe 1, temperature probe 3 parallel connections are electrically connected with a port of processor 8, and described survey draught temperature probe 4 is electrically connected with another port of processor 8 and also can be electrically connected one in the port that described oxygen measuring probe 1 is connected with processor 8 surveys CO probe 2.Oxygen measuring probe 1 among the figure, survey CO probe 2, temperature probe 3 and be arranged in the chimney 7 on the boiler 6, survey in draught temperature probe 4 combustors 5 that are arranged on the boiler 6.
As shown in Figure 2, principle of work of the present utility model is, at first configure the kind of fuel, oxygen measuring probe 1 is measured the content of oxygen in the flue then, survey CO probe 2 and measure the content of CO in the flue, temperature probe 3 is measured exhaust gas temperature, survey draught temperature probe 4 and measure intake air temperature, with follow in the above-mentioned data input processor 8 according to the boiler combustion efficiency formula treated get final product the burning efficiency of boiler.This formula is:
Wherein η represents the efficient of boiler, and Δ T represents exhaust gas temperature and intake air temperature only poor, A, and the B representative is used the relevant coefficient of fuel with boiler, and K represents the condensation loss coefficient, and the fuel coefficient difference to different so just can calculate efficient, thus display efficiency.
Claims (2)
1. online detection combustion efficiency tester is characterized in that comprising oxygen measuring probe, temperature probe, survey draught temperature probe, processor; Described oxygen measuring probe, temperature probe parallel connection are electrically connected with a port of processor, and described survey draught temperature probe is electrically connected with another port of processor.
2. according to the described online detection combustion efficiency tester of claim 1, it is characterized in that the port that described oxygen measuring probe is connected with processor also can be electrically connected a survey CO probe.
