Wide list heater used to maintain the set temperature in the room includes a group heating device for liquid fuel, which differ in the type of fuel used and, accordingly, design. The names of such heaters come from fuel used here:
- diesel heater;
- kerosene heating device;
- fuel oil unit for heating.
These devices (other than units of fuel oil), in view of the compactness, affordable cost, low fuel consumption and a relatively its low prices are a good alternative to gas heating, requiring gasification building or premises, and because popular.
These heaters are designed for space heating a large area, in which there is no gas, electric power consumption is limited or significant costs for heating is not expedient.
Consider a family of diesel heaters, consisting of different varieties of designs.
Types of diesel heaters
Heaters, operating on diesel fuel, according to the method of heat transfer performance is divided into:
- infrared heaters - emitting, all heated above a temperature of 60 degrees items radiant heat - electromagnetic waves in the wavelength range 0,5-350 microns;
- heat transfer devices such by convection and contact with surrounding objects (e.g., gender) also present, but its proportion in the total heat exchange immeasurably small - up to 8%;
- air heat gun:
- direct heating;
- indirect heating;
transferring heat by means of heated air jets directed burner.
Infrared heaters diesel-cabinets
Heating devices such performance, depending on the power used for heating large (up to several hundred square meters.) Improvement and maintaining them in the air temperature in the region of 25 degrees.
Important! The absence of such premises wall insulation is not an insurmountable obstacle - power devices diesel fuel is sufficient to provide such rooms in satisfactory conditions, even in strong frost.
The device-heater closet diesel
Cupboard heater is equipped with at least two wheels to facilitate the movement and therefore can easily be installed in the correct location. At the bottom, the closed execution of the cabinet burner located in the upper - slightly tapering upwardly pipe-coil that serves as a heat exchanger and the flue gas at the same time, the back of which the mirror is mounted reflector reflector.
The curved shape of the pipe due to the increased surface area of the radiated heat, but at the chimney has such a shape and Related drawback - shortness of the passage of smoke bending channel, so the heaters, cabinet allows the fan to force the withdrawal of the smoke coil.
Important! The design of the cabinet-combustion heater system is provided with a catalyst which increases the efficiency of fuel combustion to value that ensures the absence of odor in the surrounding unburned diesel fuel - by devices perfection to 99%.
The control system is located on the front or side panel and may be, as a touch or push button execution. Heaters have several modes of operation with automatic installation the required temperature and duration of the timer the heating. Current models are equipped with remote control function with the portable console and even a smartphone.
Features-heater cabinet for solarium
Thermal power diesel cabinet- heaters may be from several thousand to several tens thousand kcal per hour. The consumption of diesel fuel, depending on the model and power ranges from a few hundred milliliters per hour to a few liters. Consumption power device is 50 - 150 watts.
Noise-heaters cabinets usually does not exceed 50 dB.
The average price of an infrared heater, cabinet on diesel fuel is 50 thousand. rub., which is justified by its durability and application efficiency.
Air heat gun
A second type of diesel fuel heaters are air heat guns - forced heating device and directional air jet supercharging, which is the coolant.
Apparatus air heat gun - is mounted on the carriage with the fuel tank device-top burner, to a certain temperature which heats mounted in the "gun" of the ceramic heating element or metal. Upon reaching a predetermined temperature the heat exchanger includes an electric fan, is forced through the heating element cold room air.
A stream of hot air by turning the heater can be directed to a particular subject or in a distant corner of the room to reduce the side effect of dust rise. This method of heating with convection is similar when warm air after contact with the heat exchanger rises, but Air gun flow rate from the fan several times higher convective, and the jet can be any direction.
Air heat guns are distinguished by reliability, rapid heating of the premises and economy. Tank capacity is measured in tens of liters, heaters weight - several tens of kilograms (depending on power), hot air capacity is from several hundred to several thousand cubic meters per hour, the consumption of 0.5 - 5.0 kg / hour.
Current models are equipped with electronic flame stabilization and protecting against overheating a thermostat. Heat gun for diesel fuel is able to heat an area of the room in a matter of minutes in Several hundred square meters of working almost silently, and then turn off until the next cycle heating.
By design air heat gun devices are divided into direct and indirect heating, characterized by the use of comfort and accordingly costs.
Heat guns direct heating
The design of such heaters is relatively simple, so the price direct heating guns below. flame in these heaters is not isolated from the heated air, and combustion products are released into the room. Modern direct fired heaters are equipped with fuel filters, and devices that increase the fuel combustion to nearly 100%, and still aggregates of this construction are inferior in comfort operation indirect heat gun heating.
Have a better idea about the device heat gun will direct heating schematic diagram such heater construction wherein blue indicated flow of cold air, and the red - yield Hot.
Construct direct heating guns and due to their use - as a heater in rooms with temporary human presence garage, workshop, warehouse (not grocery), etc...
Heat guns indirect heating
In diesel heaters of this type burner operation insulated - it is heated inside heat exchanger and the combustion products are discharged through a chimney system (chimney) outwards. A cold air flows from the fan when contacted with the hot heat exchanger outside the housing without mixing with products of combustion which prevents their adverse effects on the composition of the air in the room and makes the operation of the machine comfortable. Therefore, the heat gun can be used for indirect heating in buildings and residential areas as the main heating means.
Conventional circuit heat gun indirect heating device is as follows:
Advantages and disadvantages of diesel heaters
In diesel heaters, regardless of the type, a lot of common virtues that do not require a detailed description - just to list:
- durability, dependability and simplicity of construction;
- mobility units;
- high speed to achieve the effect;
- easy operation and routine care;
- high power range of models;
- high automation of management;
- the possibility of selecting a device under specific operating conditions;
- efficiency;
- high degree of autonomy;
- the possibility of production of repair of many nodes with their own hands.
Deficiencies in these heaters is much smaller, but they are still there:
- raising of dust into the air jet from the fan;
- need regular periodic ventilation of premises (oxygen burnout during operation of the burner);
- the high cost of indirect heaters;
- presence in the air of combustion products from more cheap units - direct heating guns.
Operational Safety
Any modern heating device, regardless of the design rules of the art requires Security, as it uses a particular type of fuel is not only a source of heat, but also by-products their work.
Important! To avoid accidents, and premature equipment failure, the operation of diesel heaters need to perform the following safety rules:
- The heater must be grounded.
- Use on diesel heating devices other fuels other than those specified in the instruction manual is not permitted.
- Positioning heaters near flammable items, send them to infrared radiation or a jet of hot air is prohibited.
- Using space heaters unattended, leaving them included in the care of children or at night is not allowed.
- Preventive examinations and replacement of consumable parts (filters, gaskets and so on. D.) Must be carried out in a timely manner.
conclusion
To a heater that runs on diesel fuel, justify the cost of its acquisition, the purchase must be weighed against its capacity and structural characteristics real need for heating of the premises for which it is purchased, as the purchase is not enough or too powerful productive unit is fraught with unjustified expenditure.
