Ihe ndị na-atụgharị maka wayo

A na-ekekarị nzu wayo ka ọ bụrụ ebe a na-adọba ihe na square kiln. Dị ka nhazi nke ngwaahịa ndị a chụrụ n’ọkụ, e nwere lime kilns na ceramic kilns. E kewara ya na mpaghara preheating, mpaghara ọkụ na mpaghara jụrụ oyi.

N’ezie, iji okpomọkụ nke mpaghara preheating n’elu n’elu lime kiln adịghị oke elu, ma akụrụngwa nwere ike ime ka abrasion dị ukwuu na brik ndị na-emegharị ahụ mgbe a na-ere ngwaahịa ndị ahụ ọkụ, gas na-ekpo ọkụ ga-eme ka kemịkal dị njọ. corrosion na brik refractory.

Ya mere, kpachara anya mgbe ị nwere brik. Nwere ezigbo ujo ujo, nguzogide corrosion na iyi nguzogide. Jiri nnukwu brik alumina dị elu.

Mpaghara calcination na mbụ ji brik nwere nnukwu alumina dị elu. Otú ọ dị, n’ime afọ ndị na-adịbeghị anya, iji brik ndị na-emepụta ihe na-eme ka alkaline dị mma, na-adabere na ubi gas lime.
