This article will be devoted to the first model of this series, as it is most in demand at the level of domestic use.

Design characteristics of the boiler KRP-20A

The pellet boiler Kiturami KRP-20A is a double-circuit boiler with a heat exchange chamber for three flue gas passes. This solid fuel heat generating device is capable of heating a room with an area of ​​up to three hundred square meters. Not counting the fixed blocks that are included with all standard units this type, pellet boiler Kiturami KRP-20A in a "premium" configuration is equipped with auxiliary units that simplify its operation, thereby suggesting increased comfort of use.

Consists of the following components:

• bunker. As everybody pellet boilers, KRP-20A is equipped with a reserve storage bin fuel pellets in order to ensure a long-term combustion process without human intervention. This tank has a capacity of up to 150 kilograms of biofuel. This amount is enough to feed the device for a week in cool autumn time or for four days in cold weather. winter time. The height of this module is 120 cm, which ensures comfortable use without the use of various steps, ladders, stands;
• screw feed. This unit is designed to transport fuel pellets from the bottom of the conical hopper to the top, from where it moves along the corrugated element to the fuel module for subsequent combustion. The dimensions of the screw conveyor allow you to send pellets without disturbing their original shape. The conveyor operates with the help of an electric motor;
• turbocyclone burner. One of the important elements of the Kiturami pellet boiler is a torch burner equipped with a ceramic tubular electric heater. After the initial portion of fuel has arrived, the heating element, air blower and ignition of the burner occurs. Air is forced in a spiral into the combustion chamber, evenly saturating with oxygen all the fuel intended for combustion;
• heat exchanger. The heat exchange device is designed in such a way that it makes it possible for heated gases to cycle through it several times, maximizing internal heat removal;
• hot water circuit (DHW). Represents the closed complex of pipelines allowing to adjust system of hot water supply;
• mechanical cleaning mechanism of the pellet burner. The drive is designed to remove slag, scale from the main area of ​​the burner. This process occurs automatically and cyclically during the operating state of the unit;
• Control block. With its help, it is possible to assign the operating modes of the boiler, to control and adjust the cleaning of the burner, the purge of the heat exchanger. The set is equipped with a remote control.

The features also include a practical load control system, which includes:

• integrated microprocessor control unit, continuously monitoring temperature regime water and air movement to create optimal and long-lasting combustion.
• Balanced and optimized air supply for complete combustion. The fuel feeder automatically reduces the amount of fuel if the heating temperature increases, thereby saving fuel.

Pellet boiler Kiturami, advantages and disadvantages

Like any technical device, the Kiturami pellet boiler has both advantages and disadvantages. The first category includes:

• low cost. This unit has a cost two times lower than similar products from Europe;
• frugality. According to average indicators for heating a room of 100 square meters, for heating season(6 months), the consumption for the operation of the boiler is 3-4 tons of pellet fuel. For the output power, this is a decently small indicator, especially when compared with analogues from other companies;
• significant efficiency. Due to the design functionality of the pellet boiler, the maximum heat removal is observed in the internal part of the unit, which is confirmed by a low smoke temperature, and the efficiency is 93%;
• hot water circuit. Pellet boiler Kiturami is a double-circuit device. The presence of this component of the boiler makes it possible to significantly save on electric boiler. The pellet boiler Kiturami KRP-20A produces water at a 60-degree temperature, nine liters every minute;
• fire protection system. At the end of the fuel supply conveyor at the burner intake, a temperature sensor is installed, which is a preventive measure for the occurrence of ignition. If the temperature begins to exceed the permissible one, an electromagnetic damper is activated and the flame is extinguished with water located in a container specially designed for such cases;
• bulk coolant. The coolant located in the heat exchange compartment reaches a volume of 160 liters, which is twice as much as in similar models from other companies. Such an impressive volume eliminates the adverse effect of the cold outlet on the functioning of the boiler;
• pneumatic flushing of the heat exchanger. Given technical device serves to clean the heat exchanger, which is prone to contamination with tar, slag and fumes. Cleaning is carried out compressed air with a pressure of 9 atmospheres. The time interval for this procedure is regulated by the attached control unit. Based on the quality of the original fuel, cleaning is carried out weekly or once a month;
• thermostat with remote temperature sensor. This sensor allows you to control and regulate the modes of operation of the boiler and adjust the parameters while being at a distance from it.

Flaws

The disadvantages that can be found when operating the Kiturami KRP-20A pellet boiler are expressed in the following factors:

• dependence on electricity. Along with the entire range of pellet boilers, KRP-20A is also energy dependent. Electricity is needed for the operation of fans, screw motor, cleaning compressor, heating element and control unit. It should be noted that electricity consumption is negligible. The most resource-intensive in this regard is a tubular electric heater, it needs about 400 watts to ignite, however, it takes 1 minute twelve times a day;
• slag formation. The use of a flare burner and low-quality fuel in the design of the Kiturami pellet boiler inevitably leads to the formation of slag deposits on the grates. Slag is fuel particles coking in high-temperature mode.

Slag formations prevent normal functioning boiler and cause the appearance of soot, pellet costs increase by 25%, respectively, the efficiency of the device decreases. To prevent such undesirable effects, KRP-20A is equipped with an automatic grate cleaning device from caked combustion products.

Also, in addition to the listed shortcomings, there are some minor imperfections in the assembly of the device itself, but its cost more than covers these small miscalculations.

Kiturami is constantly engaged in technical development and improvement of its products, and also strives to meet all the needs in the field of heating appliances of its potential and current customers. Detail video a review on the pellet boiler Kiturami KRP-20A offers famous resource Youtube:
