Definitions
- This invention relates to systems and methodologies for detection and monitoring the build up of soot and clinker formation in coal fired power stations
- coal minerals are usually present as free ions, salts, organically bound inorganic and hard minerals.
- these minerals partly vaporized, coalesce or fragment and transforms into ash and depose on wall tube surfaces creating heat transfer reduction and possibility of clinker formation in the boiler section of power stations due to build up of high ash content, which has a low fusion temperature.
- the burning of low quality of coal also increases the build up of clinker material.
- This invention relates to systems and methodologies for detection and monitoring of the soot build up and clinker formation in coal fired power stations but not limited to them only.
- the Clinker Alarm System detects potential clinkers by being able to identify a number of parameters
- AHF Acceptable Heat Flux
- OC boiler operating conditions limitations
- Prolonged Low Heat Flux is always below AHF for particular region and is representing heat transfer below minimum required heat transfer for prolonged period and is representing sintered soot build up (clinker formation) around a particular region;
- System prioritize soot /clinker removal for affected regions.
- Clinker Alarm System will also raise an alarm for further actions as deemed necessary by the user depending on user set parameters or requirements.
- Figure 1 is a graph of heat transfer monitoring through a monitored region of the boiler over time of the present invention
- FIG. 2 shows a schematic overview of the present invention.
- an embodiment of the invention is described more fully hereinafter with reference to the accompanying drawings and description below.
- thermocouples positioned on the inner side of the centre of symmetry plain of the webs and tubes on insulation side, other means of monitoring heat build up are to be included within the scope of the present invention
- this shows the real time monitoring of the heat transfer value in a region of the boiler of the coal powered power station. Over time the build up of soot cause the heat transfer value to decrease. When it reaches a predetermined level (AHF value), a cleaning routine is initiated automatically (A t i).
- the heat transfer value may continue to decrease up till low heat transfer (PLHF) value is reached. This then begins the process of timing or monitoring for a clinker alarm event.
- PLHF low heat transfer
- Figure 2 shows the overview of the working of the present invention of a method of monitoring and detecting conditions in relation to the formation of soot build up and clinkers in the boiler section of a coal powered power station.
- the flow diagram of figure 2 shows an instrumentation (module 1), a data processing (module 2), a clinker detection (module 3), soot cleaning (module 4) and an interface monitoring (module 5).
- I heat transfer instrumentation
- IN instrumentation condition
- lc instrument calibration condition
- OC Opating condition
- AHF acceptable heat flux
- SO sulfur cleaning
- HF heat transfer deterioration monitoring module
- PLHF prolonged low heat transfer module
- HTD Heat Transfer Deterioration
- Heat transfer deterioration (HTD) and margins of each AHF, separately for each region are adjusted automatically in real time based on operation conditions & limitations (OC) as are transition or steady state of operation, power output, burner configuration, coal blend, milling coal particle size, tube pressure , place in boiler and level of high reheater spray level etc.
- OC operation conditions & limitations
- PLHF trend value is always less than AHF value for each particular region.
- PLHF trend value is a trend value of a constantly unchanged heat transfer tendency for duration of configurable time frame and number of mechanically successful soot cleaning executions (Execution must happen during that configurable time).
- the soot cleaning execution strategy is integrated part of clinker alarm monitoring system, triggered when heat transfer deterioration value reaches AHF value, for at least one segment in the region.
- Soot cleaning execution strategy is covering a selection of cleaning devices, creation of priority list for execution, monitoring execution results etc
- the Clinker alarm can be identified to the operator as a blinking red dot on the operators interface screen but not limited to it, representing potential clinker formation at particular boiler region.
- interface screen and schematic boiler configuration with all positions of heat transfer instrumentation is allowing operators to monitor clinker formation and direction of growth in real time and sound an alarm and advise operators so that other action can be taken as deemed necessary.
