Schmidt & Danielsen a/s • Establised in 1964 mainly as a service company in the refractory business withouttechnical support. • In 1985 Søren Danielsen took over and developed the company so thatwe, in the last 25 years have worked as a complete refractory buisness (Technic design, trade, and prof. execution of new orders and doingmaintanance). Mainly basedondanishcustomers but alsocarrying out jobs in hole Europa • For nearly 50 years Hasle Refractories has beendelivered Refractory bricks, castable, mortars etc. to Schmidt & Danielsen This is whatweare: • S&D is a familyownedcompany. We have 5 technical -, 2 adm. -, 2 prod.- and 10-20 installation peobleemployed. Annualturnover has beenround 4 mill€/year over the last 5 yearsperiod. This is whatwe do: • Makes refractory sollution mainly in waste- and biomassboilers, but also industri and cremationovens.
Why refractory in furnace and boilers • It was back in 1964, wherewestarted, withoutdiscussion to prevent heat from furnaces and boilers to come out in the free. • So it is also to day in manyplants. Cement, Petrochemical, etc. • In the bigplantswheretheymakeselectricity and district heat out af waste, it has change over the last 15 years. To daysplantsalmostcanfunctionwithout refractory. Bare steamboilertubeswithorwithoutInconelcladingcan do it - but, • However to make sure that the furnace and boilers runs in a proper waywithoutpoluting the suroundings, the gas coming out of the flamesshallbekeptabove 850 dg. C for 2 sec. after the last secundairy air put in. • Thisrulegoes for every type of plant makingenergy out of waste, biomas etc. Hasle materialstogetherwithourtechnologycan do it Hasle Refractories big range of low cement castables has excelentproperties. They have good alkali resistence, have excelentstrength, lowporosity and arequitegoodworkingwith. This is whatwe do: • The next slides shows some cases wherewe have takenthatbenefit and put it intoprojects.

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 goodthing to have a schedulegoing 5 – 10 years in the future so the plant ownercan 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.
