Thrust can be considered quite heterogeneous andcomplex concept that involves several factors. To guarantee the stable operation of the equipment, it is necessary to maintain this parameter at a certain level. This concerns the functioning of any boiler equipment, because the deviation in the force of thrust from the standard indicators affects the combustion of fuel and the generation of energy.
Often violations occur during installationequipment that operates on solid fuel. The problem can be solved with the help of a traction regulator, which is used in conjunction with solid fuel boiler equipment.
Instead of the preface
Today, high technologies allowdifferent means of automation, thanks to them the boiler equipment works independently, and it is almost unnecessary 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 can not be called rare. As a reason, the heater switches off automatically.
However, on sale today you can meetfairly simple automation tools that do not need electricity to work, this may include a thrust regulator, which is used in conjunction with power-driven boilers.
Description of traction force
This parameter depends on many factors, among them:
- weather;
- chimney cross section;
- gas temperature.
All this may affect the operation of the device, thereforespecific conditions must be considered individually. Another parameter that can elude the attention of consumers, but has a great influence on the thrust force, is the type of equipment. When using a gas device, the thrust force may vary slightly, the final value is stable. This is due to the fact that the flue gases have almost the same temperature.
Deviation occurs only when the chimney is heated,the value changes briefly. Solid fuel equipment demonstrates different data. To judge the impact of models on the draft is impossible. This is due to the use of different types of fuel. Heterogeneity of indicators also depends on the type of solid fuel boiler.
The device and the description of the principle of operation
The installation of the thrust regulator is quite simple, as the design, as an example, an example of the regulator RT 10, which consists of:
- handles;
- temperature corrector;
- stock;
- actuator;
- guide;
- enclosures;
- immersion sleeve;
- thermosensitive element;
- springs;
- leverage;
- chain drive;
- chains;
- handle fixing screws;
- screw mounting lever.
Depending on which design of the boilerUsed, the regulator can be installed in different places. The main condition for this is that the immersion sleeve must be in contact with the coolant. It is a temperature-sensitive element, which is filled with gas or liquid, it expands when heated. As soon as the water temperature starts to rise, the thermoelement will act on the mechanism that triggers the chain drive lever. The chain will cover the flap. Air supply in this way will be limited, the intensity of combustion is reduced. If the temperature of the water in the jacket falls, the thermoelement will open the door, which will resume air supply.
Thrust Controller Installation
Traction control can be set by youon their own. This element should be in the front or side of the equipment. Install the device must be in a special hole. Installation work is performed 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 screws can be aligned, theyit is necessary to fix and seal using special means. It is necessary to install the lever in such a way that the hole through which the chain will go out is located above the flap. As soon as the draft regulator is installed, the boiler equipment can be melted and the coolant can be brought up to the level of 60 ° С. This temperature should be set on the regulator. The lever of the regulator is connected with a chain, the flap should be approximately 2 mm or less open at the same time. When calibrating the device, the damper must be closed; this must be done manually or by shortening the circuit.
Recommendations of a specialist
When mounted thrust regulator, the followingstage, you must install a higher temperature - at around 80 ° C. If the device is calibrated correctly, then when this indicator is reached, the flap will automatically close. Mechanical thrust control is not as accurate as automatic, and the difference can reach 5 ° C. Automatic devices can be installed on the boiler, and they will not require additional human intervention.
Making adjustment
Traction control for the boiler has two typesmarkings that are used in work in different positions. If we are talking about the device RT 10, then it can be argued that its red scale is used to work in a horizontal position, and the yellow one - in a vertical position. You can adjust the product by disconnecting the lower end of the chain from the choke. The screw is loosened. After selecting the color of the scale, it is necessary to set the value of the desired temperature.
The heat generator lights up, warms up, inthe process of which is controlled by the temperature of the coolant. As soon as the temperature reaches the desired level, you should put the end of the chain on the ash pan door. When the chimney draft regulator is calibrated, the chain should be tensioned, and its free running should not be greater than 1 mm. Then the handle is fixed with a screw.
Conclusion
As soon as the setup is complete, you shouldcheck the operation of the thermostatic regulator, while the temperature can be changed by moving the handle. The operator should compare the value with the thermometer readings.
