Traction can be considered a rather heterogeneous and complex concept, which includes several factors. To guarantee the stable operation of the equipment, it is necessary to maintain this parameter at a certain level. This applies to the functioning of any boiler equipment, because a deviation in traction from standard indicators affects fuel combustion and energy generation.
Often violations occur during the installation of equipment that runs on solid fuel. You can cope with the problem with the help of the draft regulator, which is used in conjunction with solid fuel boiler equipment.
Instead of the foreword
Today, high technologies allow you to create different automation tools, thanks to them, the boiler equipment works independently, and you almost do not need to pay attention to it. But most of them use electricity, which is not very convenient. Along with interruptions in the supply of electricity, the house is filled with cold, this situation cannot be called rare. The reason is the shutdown of the heater by automation.
However, on sale today you can find fairly simple automation tools that do not need electricity to work, here you can include the traction control, which is used in conjunction with boilers with a mechanical drive.
Traction Description
This parameter depends on many factors, among them:
- weather;
- section of the chimney;
- gas temperature.
All this can affect the operation of the device, so the specific conditions must be considered individually. Another parameter that can elude the attention of consumers, but has a big impact on traction, is the type of equipment. When using a gas device, the traction force may vary slightly, the final value is stable. This is due to the fact that flue gases have almost the same temperature.
Deviation occurs only when the chimney is warming up, the value changes briefly. Solid fuel equipment shows different data. It is impossible to judge the effect of models on traction. This is due to the use of different types of fuel. The heterogeneity of the indicators also depends on the type of solid fuel boiler.
Device and description of the principle of operation
The installation of the draft regulator is quite simple, like the design, an example of the RT 10 regulator, which consists of:
- handles;
- temperature corrector;
- stock;
- actuator ;
- guide;
- housing;
- immersion sleeve;
- thermosensitive element;
- springs;
- lever;
- chain drive;
- chains;
- handle fixing screws;
- lever mounting screw.
Depending on which boiler design is used, the regulator can be installed in different places. The main condition in this case is that the immersion sleeve must be in contact with the coolant. It contains a thermosensitive element, which is filled with gas or liquid, it expands when heated. As soon as the water temperature begins to rise, the thermocouple will act on the mechanism that starts the chain drive lever. The chain will cover the shutter. The air supply in this way will be limited, the intensity of combustion is reduced. When the temperature of the water in the jacket drops, the thermocouple will open the door, which will resume the air supply.
Traction Control Installation
Traction control can be set by you yourself. This element must be located in the front or side of the equipment. Install the device in a special hole. Installation work is carried out using screw connections that can be adjusted, this aligns the element in the correct position, which can be horizontal or vertical.
As soon as all the screws can be aligned, they must be fastened and sealed using special tools. It is necessary to install the lever so that the hole through which the chain will exit is located above the shutter. As soon as the draft regulator is installed, the boiler equipment can be melted and the coolant brought to the level of 60 ° . This temperature should be set on the regulator. The control lever is connected using a chain, while the shutter should be open by about 2 mm or less. When calibrating the device, the shutter must be closed; this must be done manually or by shortening the chain.
Specialist recommendations
When the draft regulator is mounted, the next step is to set a higher temperature - at around 80 ° C. If the device is calibrated correctly, then when this indicator is reached, the shutter will be closed automatically. Mechanical traction control is not as accurate as automatic, and the difference can reach 5 ° C. Automatic appliances can be installed on the boiler, and they will not require additional human intervention.
Adjustment
The draft regulator for the boiler has two types of marking, which are used in different positions. If we are talking about the RT 10 device, then it can be argued that its red scale is used to work in a horizontal position, and yellow - in a vertical position. You can customize the product by disconnecting the lower end of the chain from the air damper. In this case, the screw loosens. After choosing the color of the scale, you need to set the value of the desired temperature.
The heat generator ignites, warms up, during which the temperature of the coolant is controlled. As soon as the temperature reaches the desired value, put the end of the chain on the ash pan door. When the chimney draft regulator is calibrated, the chain must be tensioned and its free play should not exceed 1 mm. Then the handle is fixed with a screw.
Conclusion
As soon as the adjustment is completed, the thermostatic controller should be checked, and the temperature can be changed when the handle moves. The operator should compare the value with the readings of the thermometer.
