In houses, it is rare to see a boiler thatDoes not work on natural gas or solid fuels. Basically, gas or coal apparatuses are more often installed for space heating. Oil-fired boilers, despite the fact that these are modern units with very good quality characteristics and high efficiency, for some reason, we do not use much demand. What absolutely can not be said about our neighbors living in Western European countries. They accurately know how to appreciate and save natural resources. And that is why such boilers for liquid fuel heating are much more common. Let's try to understand in detail the principle of the device of such heating units and consider their quality characteristics and types of liquid fuel.
Liquid fuel boilers used in everyday life(we will not consider industrial boilers) can function smoothly and work efficiently on different types of fuel. A rather expensive, but the most common and high-quality type of fuel is diesel fuel.
This kind of combustible raw material, unfortunately, cannotboast low cost compared to, say, gas or electricity. But the products of the processing of fuel oil or oil fuel for furnaces are already much lower than diesel fuel. True, they also have a lower heating coefficient, about 15-20 percent. Diesel oil does not require particularly careful filtration process, but fuel oils must still be very carefully driven through cleaning filters.
Fuel for boilers can be biological.If you mix diesel or petroleum oil with combustible vegetable raw materials, you can get a great view of the fuel - biofuel. Herbal raw materials are slightly similar to the characteristics of fuel oil, but they are a bit cheaper.
This type of heating fuel can be foundin organizations or private houses located in close proximity to the service station or near the automobile enterprises. And also to the territories where the equipment for agriculture is located. In such places, waste oil at least "eat a spoon." And therefore economical owners use the used motor lubricant and effectively use it to heat their premises.
Consider the principle of operation of the device that meetsfor heat exchange processes in oil-fired boilers. The combustion of liquid raw materials and the heating of the coolant in the heating equipment takes place in a device called a heat exchanger. The principle of operation of the heat exchanger is designed so that it can effectively absorb a large amount of thermal energy in the process.
Today you can find such boilers ascondensation oil-fuel units with another area for additional exchange of thermal energy, which allows to process heat from exhaust gases, turning into an additional source of heat detrimental to the nature of evaporation.
By type of material, heat exchangers are made fromcast iron or steel. Cast iron with careful handling will last more than half a century, but too heavy. But steel weighs less, but their characteristics and service life are also worse than those of cast iron heat exchangers.
Burners in such boilers are equippedadditional pumps and fans, built-in type. The pump pumps fuel from the tank and sprays it under pressure in the heat exchanger chamber. The fan is responsible for supplying the air flow in the quantity required for the correct and effective operation of the apparatus on liquid fuel. Also, the ventilation unit is responsible for removing smoke.
Torches in the units working on liquid typesraw materials - very complex and quite expensive devices. And they are extremely demanding on the quality of the fuel supplied. Rather simple and not very expensive, the complete sets of burners can work only at maximum power, and now more refined models have up to three power modes. This leads to an increase in the lifetime of the device responsible for burning, and to fuel economy.
Burners can work in most cases.only on lightweight liquid fuels. These include diesel fuel, motor oil, and biofuels. But manufacturers have gone much further, and more modern devices are already able to recycle thicker and less efficient types of liquid fuel. To do this, before feeding into the combustion device, the fuel raw material must be slightly warmed up.
For consistent work of the burner and systemheating meets automation. This allows you to efficiently and economically use fuel, as well as to cope well with the functions of heating. And at the same time, it is practically not inferior to the common types of gas or solid fuel boilers.
Many thermal units can operate autonomously.in heating systems, which are called “smart home”, only in the presence of high-quality liquid fuel raw materials. Switching automation on and off in such boilers is carried out remotely.
There are two types of such units. Single and dual circuit.
Heating equipment with one circuitperforms the function of heating only the heating system. And dual-boiler models heat both fuel and running water through the heat exchanger. But experts often do not advise choosing units that have more than one circuit. They advise to install separately the boiler and water heater accumulative action. Installation of the split-off equipment will cost a little more, but this will undoubtedly justify itself in further operation.
Heating devices can be combined. They are called "universal combined boilers."
Such boilers are able to work on all existing types of fuel raw materials. Moreover, the transition from one type to another can be made immediately, as soon as the raw materials used end.
By the type of raw materials used, the combined boilers are of four modifications.
As you know, the price is determined by the quality.As we have already mentioned, models of heating units with cast iron heat exchangers will last longer and cost more compared to boilers made of steel.
When choosing a unit, pay attention to the cost,indicated on the boiler. The price for them will directly depend on the requests of the consumer. It should be noted that the efficiency of the device and the amount of fuel it needs will depend on the cost of the brand.
The quality of the heaters was enough said. It remains to summarize.
In areas where natural gas does not pass, a heating device operating on liquid fuel feedstock will be an indispensable option.
These boilers, the price of which is from 15 to 30 thousandrubles, on average, justify the heating of the house, where the principle of heating is chosen electric or solid fuel. Permission to install and use such units on liquid fuel is not required. And the fuel consumption will only depend on the heating area, the efficiency of the heating apparatus and the brand chosen by the consumer.
So, we found out what the price of the boilers is and what they are.
