JHHX-6-type coal activity detector I. Overview: JHHX-6-type coal activity detector means coal and coke chemical reactivity of carbon dioxide, that is, under certain temperature conditions, the coal for carbon dioxide reduction ability, is a chemically stable coal One of the indicators. JHHX-6-type coal activity detector, SCR temperature controller and a gas analyzer consists of three parts, the silicon carbide furnaces, heating up fast, good insulation properties, temperature control is accurate, sensitive and so on. Two, JHHX-6-type coal activity detector main technical indicators: Furnace temperature: short-time maximum temperature using the oven temperature to 1200 degrees 1500 degrees -1300 degrees. Temperature zone: 100mm. Heating rate: 20-25 degrees / min within one hour can make furnace temperature reached 1200 degrees -1300 degrees. Silicon carbon tubes: two screw-type Φ45 / 35 × 500 / 100,40 mm reaction tube: alumina tube Φ25 / 20 × 850 mm Controller: in the 0-1600-degree range can be automated climate control. Pyrometer: platinum and rhodium - platinum thermocouple, range 0-1600 accuracy of 1.0 degrees. Power consumption: 4-5 kW. Power supply voltage: 220V ± 20V. Total weight: 90kg. Dimensions: High temperature furnace 400mm × 460mm × 980mm. Controller mm: 380 × 450 × 250. Gas storage buoy: 360 × 750mm
