End fired furnaces with regenerative air preheating

Fossil fuel heating principle:

The furnace is always fired by means of one of two burner ports located side by side in the furnace rear wall. Each burner port is equipped with 2 - 4 underport burners.
Flame from the burner port goes through combustion area of the melting end of the furnace, turns back by 1800, and combustion gases leave the furnace through the other burner port, and enter a regenerator chamber packed with regenerator packing made of refractory material. The regenerators can be designed as single pass or double pass chambers.
Refractories of regenerator packing, and regenerator walls are heated up by the passing through combustion gases. Then, in predetermined time, this cycle is reversed, and combustion air then flows through the regenerator packing of the hot chamber. Heat from the refractories is transferred to combustion air that is heated up to 1,350 0C. In the mouth of the burner port, the preheated air is then mixed with fossil fuel in controlled mixing ratio and then it burns with optimum parameters in the combustion space of the melting end of the furnace.
.High temperature combustion process with optimum parameters of flame, and a relatively long residence time of combustion gases in the furnace result in very good heat transfer to raw materials in the furnace.
These types of furnaces therefore reach one of the lowest specific energy consumption among all the fossil fuel fired furnaces.
The furnace output can be further increased by installing electric boosting equipment that is recommended also for the improvement of thermal homogeneity of molten glass in colour glass melting processes.
A bubbler system is usually installed in the area preceding the glass-refining zone. The furnace is usually charged by means of oscillating batch chargers via 1 or 2 doghouses situated immediately at the rear wall.
The melting unit technological process is fully automated and controlled by automatic control system that enables one to control sequential and continuous technological processes.
The control system offers the following standard features: Storing and sorting of historical values measured,complete library of predetermined user screen displays,graphic imaging of measured values in trend screens,printing of user reports and alarm signalling.
The working end of the furnace is designed in accordance with customer’s needs.

Brief technical parameters:

Typical applications: Container glass
Figured glass
Glass type: Soda-lime glass
Melting capacity: 30 – 500 t/24h
Melting area: 20 - 130 m2
Fuel: Natural gas, fuel oil
Specific energy consumption: 850 kcal/kg and more, which depends on the type and colour of molten glass, type of operation,melting capacity, cullet ratio, and the capacity of electric booster heating.

Refractory-technical furnace linings

Teplotechna-Prima, Ltd. designs, supplies and installs all refractory linings of industrial furnaces.

The main field of the company activities is designing, building new and repairing existing glass furnaces, of which the largest share is glass container furnaces.

Teplotechna-Prima, Ltd. cooperates with reputable manufacturers and suppliers of refractory materials only. Since initial stages of project documentation preparation is taken into account the quality of refractory materials, especially with regards to the furnaces lifetime.

Our main suppliers of refractory materials for melting end and for working end glass contact materials are RHI AG - plant REFEL REFRATTARI Elettrofussi, Motim GmBH, SEFPRO (whole group) and our main suppliers for forehearths glass contact materials are Savoie , PD Group and S.I.G.MA.

Among the main suppliers for other parts of the glass furnaces belong PD Refractories Group (fireclay, silimanite material, silica material for masonry and crowns , fireclay and silica insulation), RHI Glas (magnesite material for masonry and chamber checkers, other products for the glass industry), PROMAT (insulation), UNIFRAX (insulation), Prumyslova Keramika Ltd. (all masses, including castables), Žárohmoty Třemošná Ltd. (all masses, including castables), DSF Refractories (mullite material), Magneco / Metrel (materials for furnace repairs in operation), S.I.G.MA and many other suppliers.

As a part of design and supplies of refractory materials following services are provided by Teplotechna-Prima Ltd.: material quality inspections and incl. transport of materials from manufacturer to customer.

The material draft consultancy for lining together with customer is commonplace.

Company details

About the Company
History
Teplotechna - Prima, s.r.o. was founded in 1991 through privatisation of two state-owned companies located in the town of Teplice: Teplotechna Teplice n.p. and Uniprojekt s.p.
Teplotechna n.p. was established in 1951 as a company with a country-wide coverage. Throughout its existence, the company participated, under different names, in construction projects of glass, chemical and metallurgical plants. Uniprojekt s.p. was also established in 1951 and throughout its existence, the company participated, under different names as a cutting-edge state-owned design institute, in projects within different areas of industrial production. However, the key areas were glass, chemical, ceramic and wood-processing industries. The group in Teplice specialised in the glass industry.
In 1989, following the dissolution of the former Ministry of Building Industry, Teplotechna Teplice s.p. moved under the Ministry of Industry and during this period, the two companies were united. The union led to the foundation of Teplotechna Teplice s.p. This company was the only company in the country that was able to provide complex deliveries in the glass industry.

Present History
In the years 1989 - 1990, the company was privatised as a result of extensive social changes. The privatisation of both companies was not done selectively (through selection of so-called interesting segments of the former companies) but by a purchase of the complex material, human and sales / marketing resources and the know-how of both companies as well as their technical archives, which contained project documentation, patents and documentation about the realisation of shares from the approx. 40-year period of existence of both companies.
The Company has been kept on record by the Regional Court in Usti nad Labem since 24th July 1991.

Company Premises
The Company owns estates, which are used as the head office, factory floors, garages and warehouses for material storage. Registered Office is at No. 2859/1, J.K. Tyla Street in the town of Teplice, in northern Bohemia. The head office, design department, production preparation, logistic sector, economic sector and extensive archives are located here. The factory floors, which are used for assembly, preparation or modification of materials, as well as extensive warehousing premises (roofed and unroofed), are located in the precinct called Jaroslav, in Probostov u Teplic.
