Solid Fuel Boiler

In monophase motors having troubles in start up and continual cycle condensator , during the start up the relays that starts up the auxiliary coil or the platinums with centrifugal

The proximity switch linked to the revolution axis  by measuring the revolution cycle of the motor  , it apprises the cycles of the motor step by step to the motor protection cycle.

Motor Protection System                                            : 

A Boiler with modulation card perceives the outside temperature and reaches the most productive combustion by consumpting less fuel.

The automatic ignition provides a comfort usage, By setting the weekly programme , the boiler is to be ignited and switched off at any time during the week . The user shall not need to deal with the ignition , setting the water temperature of the boiler and switching it off.

As it may be seen clearly from the figure , the ignition is achieved via an electrical resistance device that is located into a pipe and leading to the burn pot. The ignition temperauture needed for the fuel to be ignited is between 250 C and 400 C.

Automatic Ignition                                                        :

As the outside temperature decreases , the preset water temperature of the boiler is increased or conversely when the outside temperature increases , the preset water temperature of the boiler is decreased automatically.

As there are big differences between the temperatures occuring during the day time and night time ,the outside temperature is measured in order to modulate the water temperature of the boiler.

One of the other important modulation methods of the boiler is its ability to modulate itself according to the outside temperature as there are different countries from different locations of the world.

3. Modulation according to outside temperature ;

The less is the temperature of the gas given out , the more efficient the boiler is.

The flue temperature is measured via the help of a sensor connected to the electronic card. The maximum flue temperature is set on the electronic panel.  The boiler shall not exceed the set flue temperature  by regulating the fuel feeding time and the fan speed by this way not only the level of  fire is controlled but also the limit heat  and the emission given to the environment is kept.

2. Modulation according to the flue temperature ;

The operation capacity of the boiler is decreased one by one from % 100 to % 1 . In the modulation card , the fuel feeding and the fan speed of the system is shared to 100 steps. By decreasing one by one the capacity of the boiler is minimized from % 100 to % 1 . When there is a heat demand , the boiler itself automatically increases  the fuel feeding time and the fan speed.

Modulation card reduces the fuel feeding time , it purports that the amount of fuel transported to the burn pot is lesser. The minimum air amount that is required for an ideal combustion , is managed by reducing the fan speed ( by reducing the motor cycle of the fan )This means that  the air flow blown to the burn pot is decreased.As the oxygen amount for the combustion is decreased this breeds the fire level to be shortened.

-Low operating costs

-Comparing to the full operating systems , it consumpts less electricity

-Environment friendly ( as it extends less gas )

-Fuel saving

The advantages of the modulation system ;

Thanks to this , the combustion level is minimized and the boiler is not required to operate in full operation .

When we set the boilers Preset Temperature : 55 C , the boiler shall reduce the full operation capacity by itself . This is achieved by reducing the fuel feeding time and the fan speed automatically.

According to the position of the building , the capacity is choosen ( for instance ; a 40.000 Kcal/H Boiler ) When the heat demand is less in the building , the boiler is to be operated as a 20.000 KCal/H or 25.000 Kcal/H capacity.

1.Modulation according to the set boiler water temperature ;

This is an electronic part that providing the full automation of the boiler. The steps carried out by the modulation card are as follows ;

The operation principle of the modulation card

Thanks to the modulation card , this system operates with full automation.After having loaded the fuel to the bunker of the boiler , all processes automatically managed by boiler iteself and the ash is removed out to the ash box located in front of the boiler.
