Ensuring safe operation of the boiler roomequipment is the primary task that puts staff. For its implementation using different tools, covering a wide range of nuances of operation of the units. This is the initial organization of the conditions in which the boiler room will operate, and subsequent technical measures aimed at maintaining the optimum function of the equipment. At the same time, the responsible persons must follow the rules for using the facility. As practice shows, boiler room maintenance is initially facilitated if operators rationally approach the loading of equipment capacity and regularly monitor operating performance.
General information about boiler maintenance
In general, maintenance activitiesprovide for the performance of basic operations for the diagnosis of equipment, as well as carrying out repairs. The initial level of maintenance is reduced to a set of measures aimed at maintaining the operability of the element base and the operability of the units. The fact is that a heat boiler house in any design is subjected to high temperature loads and even if the operating rules are followed, there is a reduction in the strength and functional resources of the equipment. That is, even if during the routine inspection the staff does not detect breakdowns, the detection of deterioration in detail, for example, is the reason for updating them.
Specific schedules and organizational nuances inmaintenance depends on many factors. For example, the frequency, purpose and scope of the planned work is important. The universal measures in which boiler equipment is serviced include everyday care, inspections, the elimination of minor malfunctions and the diagnosis of individual components of the system.
Repair work
Direct repair can be considered and howconsequence of the inspection, and as part of the basic service - seasonal or periodic. In any case, repair actions are aimed at restoring the health of heat engineering units or their individual parts. Planned operations of this kind are usually reduced to the prevention of breakdowns. So, if during the maintenance process suspicious elements were identified from the point of view of reliability, they are replaced during scheduled maintenance. If an accident occurs, then unplanned repairs are carried out. In this case, the boiler equipment is subjected not only to a full audit, but also to special tests. First of all, a part or all of the system complex on which the accident occurred is checked. Further, its causes are identified and measures are taken to eliminate them. In some cases, a design solution is being developed for this purpose, which gives recommendations on the replacement of failed elements. When the main repair operations are completed, the units are tested and final tests are performed during operation.
Service steam and hot-water units
These are the most common boiler units,which are used both in the maintenance of private houses and in industrial complexes. Experts in the course of primary maintenance identify possible overheating, clogging and ignition of communications. There may also be an inspection of compliance with operational standards. If industrial boiler houses are serviced, then auxiliary systems with units that can influence the functional state of the target equipment are also subjected to thorough diagnostics. By some signs, it is possible to reveal even less noticeable disturbances in the operation of boiler stations during the initial inspection. These features include the presence of noise in the combustion chamber, as well as uneven and pronounced vibrations.
In the technical part of the event is carried outtightening insufficiently reliable connections, restoring broken fences, adjusting the work of the sootblowing equipment and eliminating defective elements. In addition, maintenance of boiler rooms provides for the implementation of cleaning units. To get rid of dirt and dust, it is required not only working units, but also external surfaces of the equipment.
Repair of steam and water heating equipment
Mostly problems with this kind of equipmentarise due to the formation of dents, crevices and fistulas. Therefore, you should carefully check the communication networks associated with the boiler. For example, defective pipes can lead not only to a disturbance in the circulation of the coolant, but also to breakdowns in drum mechanisms, collectors and expansion of individual elements with their subsequent deformation. Also, experts perform an update of the fittings, check the quality of tightening of bolts and studs, eliminate the formed air suction, etc. Depending on the additional equipment, repair of a hot-water boiler room may include the replacement of defective membranes and updating of insulating materials.
Maintenance and repair of economizers
In this case, a special placemetal fittings and the integrity of the equipment frame. The tightness of the units is checked using special devices, after which it may be necessary to replace rolls, flange parts, gaskets and coils. If servicing of boiler houses with connection of water circuits is performed, then a check for leaks is included in the list of measures. And not necessarily this should be followed by the replacement of the same coils - as a rule, the identified problems are corrected by tightening loose connections.
Maintenance and repair of gas-oil burners
Оборудование, которое работает с газовыми communications, is checked for leaktightness of the injectors, as well as their connection with the basic design of the housing. In particular, the master checks the quality of the installation of the unit, the mounting nozzles, eliminates suction and traces of slag formation. In the main part of the repair work, the gas boiler room can be dismantled and disassembled into individual functional components in order to further wash the parts. Special attention is paid to the built-in nozzles, which may require replacing the nozzle.
Carrying out commissioning activities
To start, a specialist develops a map.carrying out technological operations. Further, the performance indicators are evaluated, among which are power, fuel consumption, etc. At this point, the measuring equipment should be ready, which will allow to evaluate the quality of the functioning of the system. As a rule, servicing of boiler houses in the part of carrying out commissioning activities is carried out adjusted to the recommendations of the manufacturer. If we are talking about a unit that has already been operated, then the basic data for subsequent settings can be readings from previous sessions of the equipment. Actually, the result of the commissioning test should be similar information about the testimony of the boiler room, which are expressed in operational indications.
Conclusion
Maintenance required duringall use cases of heating equipment. Testing the system for quality security is probably the most important goal of such events, but not the only one. Is that the gas boiler is serviced primarily for the analysis of the health of its components. In other cases, the financial feasibility of carrying out the same commissioning operations is of no small importance. They allow not only to correct and prevent breakdowns, but also to optimize the operation of the system in order to minimize the cost of energy consumption.
