Abstract

Calcium carbonate 4.5-5.5 wt.% (to the total wt.), sodium carbonate 0.12-0.3 wt.% and sodium chloride 0.12-0.3 wt.% are added to anthracite powder to produce the briquet which showed better combustion than the common briquet.

Description

연소효율과 가스안전성을 높인 연탄의 제조방법Manufacturing method of briquettes with improved combustion efficiency and gas safety

본 발명은 연소효율을 높이고 유독가스의 발생을 억제할 수 있는 연탄의 제조방법에 관한 것이다.The present invention relates to a method for producing briquettes which can increase combustion efficiency and suppress generation of toxic gases.

현재 제조되는 연탄은 국내에서 생산되는 무연탄의 탄질이 점차 저하하고 있으므로 표준열량을 유지하기 위하여 양질의 수입석탄을 배합해야 하는 실정에 있다.Currently, the briquettes manufactured are in a situation where coal quality of the anthracite coal produced in Korea is gradually deteriorating. Therefore, high quality imported coal is required to maintain a standard calorie.

또한 연탄에서 발생하는 아황산가스의 발생을 억제시키기 위하여 무연탄의 적정량의 석회석을 배합하도록 되어 있으나 석회석의 배합비율이 높게되면 표준열량에 미달하게 되고 다시 열량을 높이기 위해서는 수입석탄의 배합비율을 높여야 하므로 결국 생산원가를 상승시키는 원인이 되고 있다.In addition, in order to suppress the generation of sulfurous acid gas from coal briquettes, an appropriate amount of anthracite is mixed with limestone. However, when the mixing ratio of limestone is high, the amount of limestone falls short of the standard caloric value. It is the cause of raising the production cost.

연탄이 표준열량을 유지하지 못하는 다른 원인은 연탄의 연소부진으로 인하여 연탄이 연소가 완료된 후에도 연소되지 아니한 연탄이 그대로 남게 되는데 연탄의 연소성분이 충분히 연소된다면 그 만큼 열량이 증가 될 것이다.The other reason that briquettes cannot maintain the standard calorific value is that the briquettes that have not been burned remain after the briquettes are completely burned due to the combustion of briquettes. If the combustion components of the briquettes are sufficiently burned, the amount of heat will increase.

본 발명은 국내 생산의 무연탄만을 사용하여 유독가스의 발생을 억제하고 연소가 촉진되어 연탄의 연소성분이 완전 연소되게 하여 발열량을 크게 향상시키는데 그 목적을 두고 있다.The present invention uses only anthracite coal of domestic production to suppress the generation of toxic gas and to promote combustion to completely burn the combustion components of the briquettes, the object of which is to significantly improve the calorific value.

본 발명은 저열량의 연탄원료에 석회석과 더불어 소량의 탄산소오다 및 소금을 첨가하여 양질의 수입탄을 배합하지 아니하고도 연탄의 연소성분이 완전연소되도록 연소를 촉진시키며 아황산가스와 일산화탄소르 고정화하는데 그 특징이 있다.The present invention, by adding a small amount of sodium bicarbonate and salt to the low-calorie coal briquettes and promotes the combustion so that the combustion components of the briquettes are completely burned without the combination of high-quality imported coal and to stabilize the sulfur dioxide and carbon monoxide. There is a characteristic.

국내의 무연탄의 성분 및 석회석의 성분은 다음 분석과 같다.The components of domestic anthracite coal and the components of limestone are as follows.

무연탄과 천연석회석의 이러한 성분으로 인하여 연탄이 연소함에 따라 이에 첨가된 탄산소오다(Na2CO3)와 소금(NaCl)그리고 석회석의 주성분이 산화칼숨(CaO)이 무연탄 함유된 유황(S)과 반응하여 황화칼슘(CaS)및 황산나트륨(Na2SO4) 등으로 변환된다.This component of anthracite and natural limestone causes the addition of sodium carbonate (Na 2 CO 3 ), salt (NaCl), and limestone (S) containing anthracite (CaO), The reaction is converted into calcium sulfide (CaS) and sodium sulfate (Na 2 SO 4 ).

본 발명에 대한 실험에 의하면 연탄의 표준중량 3.6Kg에 대하여 석회석을 180-190g, 탄산소오다를 5-10g, 소금을 5-10g 배합하여 연탄을 제조하였을 때 통상 국내생산의 무연탄과 수입석탄을 배합하여 제조한 연탄보다 연소시간은 대등하고 발열량이 15% 증가 함을 확인하였으며 이상의 배합비율을 변경함에 따라 다소의 연소효율이 차이남을 알 수 있었다.According to the experiment of the present invention, when the briquettes were prepared by mixing 180-190 g of limestone, 5-10 g of sodium carbonate, and 5-10 g of salt with respect to the standard weight of 3.6 Kg of briquettes, the domestic anthracite coal and imported coal were mixed. The combustion time was comparable to that of briquettes prepared by the same method, and the calorific value increased by 15%. The combustion efficiency was slightly different by changing the above mixing ratio.

이러한 발열량 증가의 원인은 연소가 끝난후 연탄재를 절단해 보았을때 쉽게 알 수 있는바 기존 연탄은 연료비를 절감하게 위하여 공기공급을 제한하였을때에는 연탄재의 내부에 상당량의 연소성분이 그대로 남아있는 반면 본 발명에 의한 연탄은 동일한 조건하에서도 연탄이 완전히 연소되며 연탄재에 연소성분이 전혀 남아있지 않고 불꽃이 왕성하며 연탄재가 단단히 응결되어 있어 고열로 연소되었음을 입증해 주고 있다.The cause of the increase in the calorific value can be easily seen when cutting the briquettes after the end of the combustion bar in the existing briquettes when the air supply is limited in order to reduce the fuel costs, while a considerable amount of combustion components remain intact in the interior of the briquettes Briquettes are proved that briquettes are completely burned under the same conditions, no combustion components remain in the briquettes, the flame is vigorous, and the briquettes are solidified.
