The proper setting of a coal boiler without a feeder has a huge impact on its efficiency. Such an appliance requires proper programming so that it works not only efficiently (thus providing thermal comfort), but also economically. Learn how to set up a coal stove without a feeder, so that you can be guaranteed that it will work flawlessly during the heating season.
Wondering how to set the pre-blows in a coal stove? First of all, it is worth finding out what they even are. This is nothing more than the work of the fan to raise the combustion temperature. In models with automatically controlled blowdown, the boiler adjusts its power on its own when it is in operation and maintenance mode. However, when firing up you have to do it manually.
So how do you adjust the blowdown in a central heating furnace? By far the easiest way is to do it during firing up. This process should take place as soon as possible. At the very beginning, you should set the fans at about 5-10% power. After a while, it’s a good idea to raise it to 50-60%, so that the temperature of the furnace can quickly rise. At the very end of kindling, i.e. at its final stage, the power of the fans should be lower, maybe about 40%. This will keep the heat inside the furnace and allow the boiler to start the next modes.
During furnace operation, blowing should be frequent, but short. This will prevent the temperature from rising quickly above the selected level, and also prevent the accumulation of flammable gases in the furnace and flue pipes. Thus, regulating blowdowns also affects the safety of using the central heating system.
Controlling a boiler can be much easier if you decide to use a system for regulating its operation. In the offer of ENGO Controls, you will find both wired controllers and wireless or Internet-controlled ones. Thanks to them, your boiler will work more efficiently, as well as more economically. The controllers will help you maintain the optimal temperature level.
Before you learn how to set a coal stove controller without a feeder, find out what this device is. It allows you to automatically manage the operation of the boiler. The controller selects the parameters of the furnace so that it works efficiently and economically. This makes it possible to optimally use the fuel that has been delivered to the combustion chamber.
Such boiler control devices are primarily functional: they significantly facilitate the management of the furnace. Before you choose the right model of controller, carefully check which one will be the best choice for you. If you properly match it with the installation in your home, you will be sure that it will perform its function well.
Each coal stove controller must be accompanied by instructions for installation and use. It is essential to familiarize yourself with it, which will allow you to set the optimal parameters for boiler operation. However, you are bound to wonder how to set the coal stove controller so that its temperature is appropriate. It is recommended that its minimum level be around 55-60°C. It is also important to remember that it should not be too high. This is because it can cause overheating of the entire system, which in turn threatens to boil the open stove system. This is a dangerous situation that poses a danger to both the central heating system and its users.
Regulation of a backfired boiler is primarily aimed at making it produce the right amount of heat. This is possible by controlling the fuel supply and the air that is fed into the furnace. For boilers without a feeder, this is more cumbersome than for stoves with an automatic metering system. This is because it is necessary to control the amount of coal on an ongoing basis.
It is very important that there is neither too little nor too much fuel inside the furnace. After firing up, a small layer of coal should be placed in the stove, and only after several minutes more can be added. It is also worth remembering that the top of the added coal should be about 30 cm lower than the lower edge of the door. The amount of fuel consumed depends primarily on the weather conditions and the temperature you want indoors.
In stoves without a blower, you also need to control the air supplied to the hearth. It initially goes there through a flap located in the ash door. It is necessary for the combustion process to take place in the stove at all. How many centimeters the flap should be ajar depends primarily on the type of boiler and chimney draught. It is worth remembering that the air supply should be slightly larger when volatile substances are burned. Long, orange flames are a sign of this. However, if there is only embers in the furnace, the flap can be tilted about 1-2 mm. Many boiler models also have a secondary air inlet, which is located in the intake door. It is worth tilting it for about 2 mm when burning volatile substances.
Such models do not use a separate control system for secondary and primary air. The fan is mounted on top of the boiler or in the ash door. The air is always fed under the grate. How to set the controller of a coal stove with a blower? First of all, you need to control the amount of air supplied by setting the appropriate speed of the blower. Sometimes it also has special shutters, although this is not the rule. A properly set blower delivers the optimal amount of air. If there is too little of it, it will result in an improper rate of coal combustion, as well as the formation of soot in various areas of the boiler. On the other hand, blasts that are too strong will cause the fuel to consume far too quickly, making it necessary to constantly add to the furnace.
Proper programming of a coal boiler without a feeder has a huge impact on its efficiency, as well as on the convenience of its use. By following the principles mentioned above, you will ensure adequate thermal comfort with optimal boiler operation.
