The Poříčí Power Stations Organizational Unit consists of two plants, The Poříčí II Power Station and The Dvůr Králové Heat Power Plant.

The Poříčí II Power Station

This power station is situated in a scenic landscape of Trutnov region, at the foothill of the Krkonoše Mountains, the highest mountains in the Czech Republic, in the eastern side of the town of Trutnov.

The power plant was put into operation in 1957. Initially, six boilers were installed, with unit power output of 125 tons of steam/hour. Four out of the six initially installed boilers are now replaced by two fluidized bed boilers, each having the nominal power output of 250 tons of steam/hour. The fluidized bed boilers were put into operation in the years 1996-1998 and currently burn brown coal. Two initial boilers are used as heat power production emergency backup.

In the machine room, three turbine generators are installed, having the unit nominal power output of 55 MW. In the 70's, they were reconstructed and became consumption-condensing sets to ensure supplies of heat in hot water and steam. At present, two turbine sets are utilized and the third one stands by to cover regular supplies in case of long-term repairs (general overhauls and reconstructions). The Poříčí Power Plant supplies heat power for the town of Trutnov and a major part of its surroundings.

The heat power from the Krkonoše steam line is supplied to towns and villages in the region starting with Horní Maršov and Dolní Maršov, Jánské Lázně, through Svoboda nad Úpou, Mladé Buky, and as the last but not the least, to the town of Trutnov. The Radvanice steam line brings the heat power through the village of Lhota u Trutnova to a mining village of the same name and further on to the village of Jivka. In the south direction, a hot water line goes from The Poříčí II Power Plant to the town of Úpice, supplying along the way environmentally friendly heat power, additionally, to villages of Bohuslavice, Adamov, and Suchovršice.

The Poříčí II Power Plant features the total heat power output of 294 MW. Annually, it delivers through its steam network (38 km total length) and hot water network (35 km total length), approximately 1,500 TJ of heat power to consumers at 1,400 primary points of acceptance. Out of the volume, 35 % goes to residential heating and 65 % is consumed in non-residential heating applications.

From the viewpoint of electricity production, The Poříčí II Power Plant belongs to the so-called system power plants. Thanks to its location, it plays an important role in maintaining good voltage conditions within the north-east region of the Czech Republic.

The Dvůr Králové Heat Power Plant

The Dvůr Králové Heat Power Plant was constructed at the beginning of the 50's, as the central heat resource of the town of Dvůr Králové nad Labem, and replaced inadequate local resources in the town. The first deliveries of steam for industrial plants commenced towards the end of 1955.

The installed heat power output equals to 115.8 MW. Annually, the total volume of 800 TJ, approximately, is supplied from this heat power plant, through a steam network of 11 km total length to 100 points of acceptance. Out of the volume, over 11 % is supplied for apartment heating.

Since 1996, all heat power production units with output exceeding 6 MW must comply with strict criteria, determined in the air pollution control act. The same applies to operation of The Poříčí Power Plant Organizational Unit. The concept of electricity and heat combined production itself provides for more efficient utilization of power contained in coal, and therefore results in smaller amounts of pollutants released to the air, per unit of power produced. In addition, there are other technology measures adopted in The Poříčí Power Plant, leading to a reduction of electricity and heat production negative impacts on the environment. In particular, they include construction of the two fluidized bed boilers in The Poříčí II Power Plant, mentioned already, as well as the primary measures adopted in two initial 125 t/hour boilers, which together with combustion of quality sulphur low-contents coal ensure compliance with emission limits required by the law, in covering emergency situations.

In The Dvůr Králové Heat Power Plant, the main boilers were reconstructed to provide for an optional natural gas scorching. Here, new special cloth filters were erected, providing for a precipitation of dust particles from flue gases. In this case, too, low sulphur contents coal is only burnt. Additionally, boiler combustion control systems were totally reconstructed. This all enables a continuation of particular The Poříčí Power Stations' technology operations under the strict requirements newly applicable to the air pollution control.

Combined production

Our company's pride is the fact that it produces electric energy as well as heat energy by using combined production technology in its own environmentally friendly resource. This production technology, also called cogeneration, enables the most effective utilization of energy from the fuel; a part of energy gained from steam is firstly used for production of electricity, and secondly for supply of heat to centralized heat supply networks.

Provable economical and ecological advantages of the production technology, being used by us, are of entirely essential character, and because they are based on the physical principles, they have a permanent validity.

When using classic method of an independent production of electricity, the higher part of heat is handed over, without any effects, to cooling water, and then to the surroundings. This waste heat represents an environmental load to landscape, increases volume of primary fuel, and it results in a higher leakage of pollutants to atmosphere.

Use of cogeneration method of production means savings of up to 32 % of the loaded-in fuel and participates, to the same extent, on the landscape ecological load reduction.

Effects of the combined production of electric and heat energy in The Poříčí Power Station are quite clearly provable, not only in economical but also in ecological point of view. Development of centralized heat supply from The Poříčí Power Station resulted in Trutnov region in removal of local fireplaces and district heating stations, as well as in reduction of the emitted sulphur dioxide contents by 2,600 tons yearly. This represents 118,000 tons of brown coal from the local fireplaces that would otherwise load the air in the region.

The completed ecologization of our production equipment has resulted in a favourable impact to air cleaneness in the locality.

Heat energy

Our company not only produces heat energy (in combined production cycle together with electric energy) but also distributes it, by means of the existing centralized heat supply systems, in most cases to the end-user points of acceptance. We consider this fact as essential. By elimination of the distribution connecting link, we manage to provide a high level of our services. Team of professionals draw a maximum attention to Centralized Heat Supply network (own or hired) for ensuring the reliable operation at as lower as possible heat losses, and also in viewpoint of efficiency of the invested financial means.

We consider the delivery of heat energy to the end-user point of acceptance as one of the key tools for maintaining not only the acceptable price level of our services but also its quality and reliability. Our target is not only the satisfied but the faithful customer who cannot imagine his life without our services.

We supply heat energy for heating, preparation of hot service water, air-conditioning as well as technological purposes.

We offer a free capacity in supplies of heat energy to all those who own the object in the surroundings of our heat networks, and to all those who have to make decision which resource of energy is to be selected. Please do not hesitate to contact us, we will be glad to help you solve the problem of providing heat energy.

Secondary power-producing products

When producing electric and heat energy from coal, there are generated the waste products that have been stored at the disposal sites in the past years. During construction of the new technological equipment - fluidized bed boilers in The Poříčí Power Station, there was also built an equipment for a dry ash take-off. The waste, previously unusable, is changed to a secondary raw material the transport of which can be effected by railway or trucks.
