Boiler equipment

In winter, the greenhouse is a great haven for plants sensitive to cold. However, during frosts and there you need to warm them. This can be done using a boiler plant .

Coal, electricity or gas?

Wood boilers are still very popular. However, this is not a very convenient solution, since it is necessary to control the device 24 hours a day - otherwise the furnace may go out. It is more convenient (although more expensive) to heat the greenhouse with the help of electric radiators (oil or convectors), radiators or heating cables (in small rooms). Also, sometimes they buy a diesel boiler or a diesel fuel boiler .

The heat source can also be a gas boiler , which heats the water transported to the greenhouse and distributes heating pipes and radiators in it. This is one of the best heating methods, both in terms of comfort and environmental impact. The system works efficiently without interference and also allows you to precisely control the temperature

The greenhouse can also be heated using a gas heating boiler powered by natural or liquid gas. There are models of various sizes available on the market, portable and permanently installed in a turnkey boiler room . They allow you to heat the room very quickly, especially during severe frosts.

Boilers, burners and the entire heating system are designed specifically for greenhouses. The boiler has a large water volume. The design of the primary combustion chamber of the burner provides a low emission of NOx and CO, which allows the gases to be fed into the greenhouse to feed CO2 plants. The system has a very economical gas consumption. In ATS-Ukraine, you can buy boiler equipment or order the installation of boilers for your industrial greenhouse.

The principle of operation of the gas heating boiler

In the exhaust system, a flue gas condenser (economizer) is installed behind the boiler. First, the condenser is used to cool the flue gas to supply CO2 (from 120 to 60 ° C). Exhaust gases - CO2 - are taken directly to the condenser and sent to the plants in the greenhouse. Carbon dioxide is one of the main fertilizers for plants.

The installation of heating allows to obtain latent heat from flue gases, which gives an economic effect. The temperature difference is used as additional heat during heating.

greenhouses.

Combined heating boilers are equipped to work on gas and diesel (as a backup fuel in case of gas interruptions). For heating the greenhouse, we suggest installing a boiler or several “Crone” boilers or similar to the combined RKB burners.

A system of plastic CO2 pipelines (PVC) is used to distribute condensed flue gases. For the transport of flue gases, a centrally mounted fan installation is used. In an enterprise with several compartments, it is possible that several CO2 control valves are open and less flue gas is required. The fan is equipped with a frequency regulator and a pressure sensor that measures the pressure in the discharge pipe. Thus, there will be the same pressure in the system, and thus the distribution of flue gases will be guaranteed correctly. In addition, a mixing valve is provided in the fan installation. When starting the system, ventilation is first carried out using cold ambient air. When CO2 metering from the boiler is allowed, the mixing valve starts to open slowly. A special thermostat ensures that the temperature of the flue gases does not exceed 55 º C. The maximum temperature of PVC is 63 º C. The request for CO2 is determined by the climate computer or the measuring system, if necessary it is supplied separately.
