Schmidt & Danielsen a/s –Establised in 1964 mainly as a service company in the refractory business without technical support. –In 1985 Søren Danielsen took over and developed the company so that we, in the last 25 years have worked as a complete refractory buisness (Technic design, trade, and prof. execution of new orders and doing maintanance). Mainly based on danish customers but also carrying out jobs in hole Europa –For nearly 50 years Hasle Refractories has been delivered Refractory bricks, castable, mortars etc. to Schmidt & Danielsen This is what we are: –S&D is a family owned company. We have 5 technical -, 2 adm. -, 2 prod.- and 10-20 installation peoble employed. Annual turnover has been round 4 mill /year over the last 5 years period. This is what we do: –Makes refractory sollution mainly in waste- and biomass boilers, but also industri and cremation ovens.
Why refractory in furnace and boilers –It was back in 1964, where we started, without discussion to prevent heat from furnaces and boilers to come out in the free. –So it is also to day in many plants. Cement, Petrochemical, etc. –In the big plants where they makes electricity and district heat out af waste, it has change over the last 15 years. To days plants almost can function without refractory. Bare steamboilertubes with or without Inconel clading can do it - but, –However to make sure that the furnace and boilers runs in a proper way without poluting the suroundings, the gas coming out of the flames shall be kept above 850 dg. C for 2 sec. after the last secundairy air put in. –This rule goes for every type of plant making energy out of waste, biomas etc. Hasle materials together with our technology can do it Hasle Refractories big range of low cement castables has excelent properties. They have good alkali resistence, have excelent strength, low porosity and are quite good working with. This is what we do: –The next slides shows some cases where we have taken that benefit and put it into projects.

How to make functional maintanence and service at refractory Make good solution at start. Good materials, good anchoring, correct expansions etc By every stop make sure that expansion joints are in good shape and not filled with slag. Put in new expansion materials. By every inspection make notes on the drawing if any repairs has been made and make a forcast for next revision, so it could be prepared. Its a good thing to have a schedule going 5 – 10 years in the future so the plant owner can have it in his budget.
Can Hasle Refractories LCC materials been given a longer life time? With good and planed service – yes. With good and carefull operation of the plant. Avoid high peaks, avoid melted slag. Pre-protection of a lining has been tried before. Lately test have been carried out to make LCC construction more gas teight, –After drying out the materials to 110 dg the surface is cured by spraying the material on the surface. It penetrate and fill out all smaller holes and chracks –After heating it up again the surface is given a 2 layer coating. –This can be done the year aften when the plant is out of operation. It has been testet by the Danish manufacture company at a plant in sweden. We have cured tiles for 1 of the AET plants and the costumer have ordered the same curing for next delivery. They are very satisfied with the tiles compared with tiles witout coating.
