Ensuring the safe operation of boiler equipment is a top priority for service personnel. For its implementation, various means are used, covering a wide range of nuances of the operation of the units. This includes the initial organization of the conditions in which the boiler room will operate, and subsequent technical measures aimed at maintaining the optimal function of the equipment. At the same time, responsible persons must comply with the rules for using the facility. As practice shows, the maintenance of boiler houses is initially facilitated if operators rationally approach the utilization of equipment capacities and regularly monitor performance.

General boiler maintenance information

In general, maintenance activities include the implementation of basic equipment diagnostics, as well as repair activities. The initial level of maintenance is reduced to a set of measures aimed at maintaining the he alth of the element base and the performance of the units. The fact is that a thermal boiler house in any design is subjected to high temperature loads and even subject to compliance with operationalof the rules, there is a reduction in the strength and functional resources of the equipment. That is, even if the staff does not reveal any breakdowns during the scheduled inspection, the detection of wear in parts, for example, is a reason to update them.

Specific schedules and organizational nuances in carrying out maintenance depend on many factors. For example, the frequency, purpose and volume of planned work matters. The universal measures within which boiler equipment is serviced include daily maintenance, inspections, elimination of minor malfunctions and diagnostics of individual system components.

Repair work

Repair itself can be considered both as a result of the inspection, and as part of the basic maintenance - seasonal or periodic. In any case, repair actions are aimed at restoring the operability of heat engineering units or their individual parts. Scheduled operations of this kind are usually reduced to the prevention of breakdowns. So, if during the maintenance process suspicious, from the point of view of reliability, elements were identified, then they are replaced during a scheduled repair. If an accident occurs, then unscheduled repairs are carried out. In this case, the boiler equipment is subjected not only to a complete revision, but also to special tests. First of all, a part or the entire complex of the system on which the accident occurred is checked. Further, its causes are identified and measures are taken to eliminate them. In some cases, a project is being developed for this.a solution that gives recommendations on the replacement of failed elements. When the main repair operations are completed, the units are tested and final tests are carried out during operation.

Maintenance of steam and hot water units

These are the most common boiler units that are used both in the maintenance of private houses and in industrial complexes. During the initial maintenance, specialists identify possible overheating, clogging and fires in communications. Verification of compliance with operational standards may also take place. If industrial boiler houses are serviced, then auxiliary systems with units that can affect the functional state of the target equipment are also subjected to thorough diagnostics. According to some signs, it is possible to identify violations in the operation of boiler stations that are less noticeable during the initial examination. These signs include the presence of noise in the combustion chamber, as well as uneven and pronounced vibrations.

In the technical part of the event, insufficiently reliable connections are tightened, broken fences are restored, soot-blowing equipment is adjusted and defective elements are eliminated. In addition, the maintenance of boiler rooms also provides for the cleaning of units. Getting rid of dirt and dust requires not only working units, but also the external surfaces of the equipment.

Repair of steam and hot water equipment

Mostly problems with this kind of equipmentoccur due to the formation of dents, cracks and fistulas. Therefore, the communication networks connected to the boiler should be carefully checked. For example, defective pipes can lead not only to a violation of the circulation of the coolant, but also to breakdowns in drum mechanisms, collectors and expansion of individual elements with their subsequent deformation. Specialists also update fittings, check the quality of tightening bolts and studs, eliminate the resulting air suction, etc. Depending on the additional equipment, the repair of a hot-water boiler may include the replacement of defective membranes and the renewal of insulating materials.

Maintenance and repair of economizers

In this case, a special place is occupied by metal 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 the coils, flange parts, gaskets and coils. If boiler rooms are serviced with the connection of water circuits, then the check for leaks is also included in the list of measures. Moreover, this should not necessarily 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 oil-gas burners

Equipment that works with gas communications is checked for tightness of nozzles, as well as their connection with the basic structure of the body. In particular, the master checks the quality of the installation of the unit, the fastening of the nozzles, eliminates suction and tracesslag formation. In the main part of the repair work, the gas boiler house can be dismantled and disassembled into separate functional components in order to further flush the parts. Special attention is paid to built-in nozzles, which may require nozzle replacement.

Commissioning activities

To begin with, the specialist develops a map of technological operations. Next, performance indicators are evaluated, including power, fuel consumption, etc. By this time, measuring equipment should be ready, which will allow you to evaluate the quality of the system. As a rule, maintenance of boiler houses in terms of commissioning activities is carried out, adjusted for the manufacturer's recommendations. If we are talking about a unit that has already been in operation, then the basic data for subsequent settings can be readings from previous sessions of equipment operation. Actually, the result of the commissioning test should be similar information about the indications of the operation of the boiler house, which are expressed in operational indications.

Conclusion

Maintenance is required in all cases where heating equipment is used. Checking the system for the quality of security is perhaps the most important goal of such activities, but not the only one. Unless the gas boiler house is serviced mainly to analyze the he alth of its components. In other cases, it is importantthe financial feasibility of carrying out the same commissioning operations is also important. 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.
