TBTXRY-1A is used to determine calorific value of combustible materials(heat capacity is 14000~15000J/K) such as petroleum products without water(gasoline, jet fuels, diesel oil and fuel oils), coal, coke and paraffin, etc.
1.The device adopts sealed oxygen bomb. The whole structure adopts stainless steel material. The strength is enough to resist the max pressure (60~70 atmospheric pressure) when the solid burning. It can resist the bigger pressure when liquid fuel burning;
2.The inner water cylinder is full stainless steel material. The cross section is pyriform and the capacity is 3kg;
3.The water cylinder is equipped with electric stirrer inside which ensures the uniform temperature;
4.The external water jacket is double layer container. It filled with water when doing determination. It make the water temperature in the cylinder uniform by water jacket stirrer and form the constant temperature environment meeting the requirements of test.
