Abstract

The invention relates to the field of calorimetric measurement of the heat of combustion, in particular, to devices for calorimetric combustion of liquid organometallic substances, and can be used in industry and energy. The purpose of the invention is to increase the completeness of combustion - it is achieved by equipping the device with a heat transfer silver tube with petals, put on the burner, and silver wire with a spiral above the burner nozzle and a heat-insulating quartz test tube. 1 hp f-ly, 1 ill.

Description

The invention is related to the field of calorimetric measurement of the heat of combustion in oxygen of liquid element-organic substances that form a solid combustion product, and can be used in industry and energy.

The purpose of the invention is to increase the completeness of combustion.

The drawing represents), but the device.

The camera body 1 (with a capacity of at least 250 cm), having the shape of an electric incandescent lamp, is made of quartz or Pyrex glass. A quartz burner 2 with a wick 3 and a sample of combustible liquid substance 4 is placed in the chamber. Silver is put on the burner on the tube 5, inserted together with the burner in the quartz tube 6. The chamber is hermetically sealed at the bottom; It is covered with a metal cap 7 with rubber gaskets, on which a quartz tube 6 is attached. The current leads 8 are insulated through the cap.

Oxygen is introduced into the chamber through a glass tube E, and the combustion gases are removed from the top through a glass tube 10 connected to the coil .11 from a copper tube.

The wick 3 is made of asbestos cord and glass wool. The silver on the tube 5 is put on the burner and its upper end, cut along several strips-petals 12, which coi are chickens at a right angle from the center. The burner nozzle is located 1-5-2 mm below these strips. Silver on Provosp

Lock 12 is introduced in parallel with the wick to the bottom of the tank and its upper part, located under the nozzle, is designed as a spiral.

The device works as follows.

A sample of a liquid element-organic (for example, organosilicon material is introduced into the reservoir of burner 2 and a wick 3 is inserted. Silver is put on the burner on tube 5. Then silver is introduced into the burner on the wire with spiral 13. The burner nozzle is closed (to prevent evaporation of the liquid) with plastic The cotton thread 15 is pulled out of the film i onto a nichrome spiral of filament 16. This serves to ignite the sample. The assembled burner with devices is inserted into a quartz tube 6 which is attached to the metal stainless steel cover 7 is introduced into the combustion chamber 1. The chamber, together with the copper coil, is installed in the bomb calorimeter vessel instead of the bomb. The vessel is filled with distilled water and placed in the calorimeter.
