Operational and adjustment tests (RNT) of boilers:

1) Drawing up and agreeing with the Customer on a program for operational testing of boilers; 2) Adjustment of boilers in accordance with the test program under technological load: 30%, 55%, 75%, 95%; 3) Detection of air suction into the furnace and flue ducts of boilers; 4) Determination of technical and economic parameters (gross efficiency, heat losses, specific fuel consumption per 1 Gcal of generated heat), environmental (O2 concentration; CO; NO; SO2 in flue gases) and operational indicators of boilers; 5) Determination of the actual aerodynamic resistance of the air and gas path of boilers; 6) Determination of the optimal fuel-air ratio for setting up automation systems; 7) Issuing recommendations and measures to improve the reliability and efficiency of the main and auxiliary equipment; Processing of test materials, preparation and issuance of technical reports valid until the next equipment adjustment; 9) Registration of regime maps, in accordance with the Guidelines for drawing up regime maps of boiler installations and optimization of their management (RD 34.25.514-96) for maintenance personnel, indicating optimal operating modes, valid for 5 (five) years until the next equipment adjustment .

What does the boiler operating map display?

Almost all indicators, which, as a rule, consist of this document, are indicated in percentages.

These indicators provide us with the following data:

gases in percentage: carbon, oxygen, carbon monoxide;
the volume of gas that is located outside the boiler structure;
efficiency factor of the unit (gross, net);
the amount of heat losses that accompany the process of burning fuel (including gas);
amount of heat loss due to chemical underburning;
the percentage of heat that is lost when the heaters operate.

These are only the main indicators in the boiler operation chart; there are several additional ones:

the volume of steam that is formed over a certain time period;
steam temperature at outlet;
air pressure in burners;
gas pressure.

All indicators have their own units of measurement - degrees, for example, pascals, etc. All boilers must have regime maps.

Example of a boiler operating map

Such cards are needed for the competent operation of gas and steam devices, as well as water heaters.

The main advantage of this document, which allows you to monitor the performance of the unit, is that when using it, you can independently observe all functional changes. Let’s say you can understand the degree of air pressure required for a certain load on the equipment. In addition, the fuel must burn completely and the equipment must be safe.

Who develops and approves the boiler operating map and other nuances

To fill out such a document, it is necessary to carry out quite a lot of tests and measurements, and they are carried out during manufacturing and commissioning. There are special companies that carry out commissioning and commissioning work. So they are doing testing. This is carried out every three years, but other auxiliary calculations are also possible.

The operating maps of hot water boilers themselves are, by and large, an ordinary table, which consists of a certain number of columns (from 2 to 5). The quantity depends only on what specific operating modes a particular model of the unit will be adapted to. There can be several of these modes:

30 %;
50 %;
79 %;
100 %.

As for the number of lines, it is quite difficult to indicate it with accuracy, because they will display all the previously indicated indicators separately.

It is worth remembering that the unit of measurement when specifying parameters is in the first column; it does not require a separate column.

In addition, the map can be presented in the form of a graph, but it is not often encountered due to its specificity and inconvenience.

Boiler operating cards are not produced in single copies. There must be at least two of them, possibly more, and one document must necessarily accompany the boiler, often in the form of a sticker on it. When you doubt the safety of the card, make yourself a couple of copies. And for the user’s complete trust in this document, it is desirable to have the company seal of the organization that carried out the commissioning procedures.

Boiler operating map

Any technical device requires careful handling, which is only possible with conscientious adherence to the user instructions developed by the manufacturers. For this reason, you should not throw away anything that is included with the new device - if you yourself cannot do what is written in the instructions, then this information will be needed at least by the specialists who will help you. This is especially true for equipment that has a fairly long lifespan - washing machines, televisions, heating boilers, and so on. And one of such documents related to this category of devices is the boiler operating map.

It is because of this piece of paper that the correct and, most importantly, efficient operation of equipment intended for heating water is possible. It is compiled according to the standard form adopted back in the USSR in 1984.

What should be displayed on the regime map?

Almost all the indicators that actually make up the boiler operating map are shown as percentages. The following data shows us such indicators.

The ratio of the following gases in percentage: oxygen, carbon monoxide, carbon.
The volume of gas located outside the boiler device.
Efficiency of the heating device (gross, net).
What are the heat losses that accompany the process of burning fuel (in particular, gas).
What are the heat losses caused by chemical deficiencies?
Finally, what percentage of heat is lost during the operation of heaters.

These are just the main indicators in the map, but there are a number of additional ones.

The volume of steam produced over a certain period of time.
What is the temperature of this steam when it leaves?
What is the air pressure in the burners?
What is the gas pressure?
