Description
Technical field
The utility model belongs to boiler safety field, especially a kind of monitoring burn-out-proof equipment for drying in real time.
Background technology
When boiler loses feedwater supplement in the operating condition, even if fuel shutoff inputs, the amount of stored heat in boiler still can
Flue gas is heated, flue gas continues the heating surface in heating boiler again, and heating surface cannot be cooled down because losing feedwater supplement, finally surpassed
The temperature in use of metal permission is crossed, such case is referred to as dry combustion method.Boiler dry combustion method can cause heating surface metal material permanent destruction, make
Damaged into boiler plant, bring economic loss.
Boiler dry combustion method is avoided it is necessary to ensure that boiler has enough feedsupplies, until boiler be cooled to safe temperature with
Under.Boiler dry combustion method is avoided mainly there are two kinds of means, one kind is cooled down by remaining feedwater in boiler.Another kind is to set
Emergency feedwater chestnut, start the chestnut when accident occurs to boiler replenishing water.When the feedwater off-capacity of drum savings, or for not having
Have a direct current cooker of drum, start emergency feedwater pump during failure to boiler supplementary feed, until boiler be cooled to safe temperature with
Under.Nowadays conventional way is to go inspection to overhaul with manpower, increases workload.
Utility model content
The purpose of this utility model is to propose a kind of monitoring burn-out-proof equipment for drying in real time, and it can be before accident generation certainly
