Assay Furnace Product Fire Assay Furnace
1.Ash Blowing Furnace Function
This equipment is specifically designed for the ash blowing process in fire assay analysis, featuring a doorless ash blowing function. Ventilation and oxygen supply pipelines are located at the rear lower part of the furnace, and together with a high-pressure blower and flow control valve, the air velocity during ash blowing can be precisely adjusted.
2.Electric Top-Opening Door with Dual Control Modes
The furnace door is pneumatically controlled for opening and closing, compatible with both automatic and manual control. It is equipped with an operating handle and foot switch for easy manual opening in case of debugging or malfunction. In the event of unexpected gas or power outages, the furnace door remains in its original position and will not fall, ensuring operational safety. The door design of this ash blowing furnace considers both safety and convenience in laboratory settings.
3.Fully Automatic Visual Observation System
The Fire Assay furnace door features an ash blowing observation window, measuring 50mm × 80mm. The observation window’s structure, from the inside out, consists of a stainless steel mirror panel + double-layered insulated glass + camera bracket + dual cooling fans. The stainless steel mirror panel is closed by default and automatically opens when observation is required.
4.Smoke Collection and Exhaust System
Equipped with a 304 stainless steel smoke hood, it collects smelting fumes from the furnace entrance. The smoke hood is detachable from the furnace body.
5.Touchscreen Centralized Control for Intuitive Operation
The control panel features a 7-inch touchscreen displaying real-time temperature, temperature range number, time interval, remaining time, output power percentage, voltage, current, and other parameters. It also includes traditional control components such as an intelligent temperature regulator, power switch, main heating start/stop button, voltmeter, ammeter, and computer interface to accommodate different operating habits.

Fully Automated Visual Fire Assay Furnace– Frequently Asked Questions (FAQ)
- What is an ashing furnace?
An ashing furnace is a box-type furnace designed to burn materials at strictly controlled temperatures. Air is drawn into the furnace through a tall chimney and forced through the insulation layers, thus being preheated before entering the furnace.
- What is a fire assay ash blowing Assay Furnace Product Features?
A ash blowing furnace is mainly used for the testing and analysis of precious metals such as gold, silver, and platinum. It separates precious metals from base metals by placing samples in an ash hopper for high-temperature oxidation.
- What is the ash blowing method?
Closed-door ash blowing. It has internal ventilation and oxygen supply piping. The air inlet is located at the lower back of the furnace. A high-pressure blower with a flow control valve controls the air intake to regulate the ash blowing speed.
- How many air inlet channels are there? What is the material?
There are four (two on each side). The air inlets are equipped with filters and are made of 304 stainless steel. The air intake volume is 330 Nm³/h.
- What are the exhaust requirements?
The smelting fumes emitted from the fume hood and furnace are collected and discharged into the main fume duct of the workshop through a single interface, equipped with a 304 stainless steel exhaust hand valve. The exhaust volume is 330 Nm³/h.
