What coal is used for heating

Any expert in heating systems will say that the choice of heat source follows from the calculation of the availability and cost of fuel. Therefore, you should not be upset if you did not have time to stretch the gas pipeline near your house or the propane-butane gas station is too far away.

In almost every region of our country, coal can be used to heat homes and utility rooms. New equipment makes it possible to combine it with electricity, increasing the comfort of using fuel.

Below you will learn more about coal furnaces for heating, for example, how they are fundamentally different from modern solid fuel boilers. And there will be recommendations for heating the house using each of the device separately.

Heating with coal

Unlike gas or oil-fired boilers, in this case, the use of automatic control of the temperature of the coolant can be done only in combination with electric heating elements.

For example, after the fuel burns out at night and when the coolant cools to a certain temperature, they begin to maintain the heating circuit.

Otherwise you will always have to be on guard with this system, especially if the fuel is not of the best quality.

Tip: the better the coal, the fewer bookmarks per day will need to perform.

1. Do not forget about the readings of instruments showing the temperature of the coolant, as well as about its level in the system. Otherwise, it will boil, which will have a bad effect on all elements of the circuit, especially if the pipelines are made of polypropylene.
2. Uneven burning of the fuel will affect the temperature drops.
3. If you do not periodically clean the ash pan and the combustion chamber with your own hands, the draft in the boiler and the furnace will decrease, because of what may happen smoke room.

Advice: we recommend choosing household coal-burning boilers for heating commercial and residential premises.

Features of the equipment

1. The main advantage of solid fuel boilers and furnaces - their versatility. In addition to coal or with it, they can burn wood, peat, household garbage, coal and wooden briquettes, sawdust and pellets for heating.
2. In addition, a corner heating stove can simultaneously or separately heat a house and be used for cooking.
3. Devices of long burning possess one more important advantage - a long period between bookmarks of fuel. Therefore, such heating equipment can operate for a long time without human intervention.
4. Coal heating boilers and stoves are easy to use - you only need to throw fuel into the combustion chamber in time.
5. The efficiency of the system using the boiler depends on the correctly calculated volume of the coolant and the quality of the fuel used.
6. The heat transfer coefficient of devices above 92%.
7. It is possible to use furnaces and boilers for heating with coal without interruption throughout the heating season.

It must be said that the heating boilers on the corner of the old model are much inferior to modern models, the development of which took into account the maximum level of heat transfer with a minimum amount of fuel. The latter are able to effectively heat various types of rooms, spending almost half as many resources.

The principle of operation of the equipment

1. The work of a coal boiler resembles the burning of a regular candle when the fuel starts and continues to burn from top to bottom. Because of this, the time of one bookmark increases and its maximum utilization takes place.
2. The heat released during this envelops the heat exchanger made of steel or cast iron. The first is cheaper, the second is more durable.
3. Air enters the combustion chamber from the bottom through the blower in a natural way or is blown from above by a special fan. Due to the large volume, sometimes up to 500 liters, the firebox can accommodate a large amount of fuel that will heat the house for a long time.
4. Sensors are provided to monitor the temperature of the coolant. They can be semi-automatic and cover the ash pan door with high liquid parameters.

Coal brand and its consumption

One of the main questions of this type of heating is which coal is better for heating, meaning its brand. Most experts are inclined to believe that this is anthracite because of its high calorie calorific value.

At the same time, it cannot be used in “Buleryan” type furnaces for the same reason, only brown coal is suitable for them. In almost any region, you can buy either one, or both, or both. Offer it to consumers with delivery.

Fossil coal brands that are used for heating:

When calculating the consumption of coal for the heating season, we recommend using a measure - a bucket, the weight of which will be about 18 kg.

Take for example a house of up to 200 m² (about a day):

• in September-October - 1 bucket;
• in November-February - 10 buckets;
• in March-April - 1-2 buckets.

The total number of buckets for the period from September to April inclusive will be 580, which must be converted into kilograms: 580 x 18 = 10,440 kg.

There is a scientific method, when about 200 g of coal is required for 1 kW of energy. Average consumption for one heating season at home at 200m² will be about 50,000 kW, which must be multiplied by 0.2 kg. The result - 10 tons will be almost similar to the previous one.

Tip: before buying coal, be sure to recognize its brand, as they have different heat emission.

Conclusion

The use of coal to heat a house is used for a long time, during which the fuel has shown itself only on the good side, especially if there is no alternative nearby. The only task for the consumer is to choose his brand correctly in order to obtain the required calorific value.

We also recommend having a good house insulation so as not to waste such expensive energy today. Video in the article will provide an opportunity to find additional information on the above topic.
