1. What is the normal color of the gas from a generator using bituminous coal as raw material?

Answer: The normal color of the gas produced from the furnace using bituminous coal as raw material is thick yellow.

2. What are the most important parameters displayed by the gas generator instrument?

Answer: 1) Saturation temperature; 2) Saturation pressure; 3) Furnace temperature; 4) Furnace pressure; 5) Pressure machine inlet pressure; 6) Insulator box temperature.

3. What are the three elements of gas stove operation?

Answer: 1 Add coal; 2 Ash removal; 3 Saturation temperature

4. What equipment should a gas protection station be equipped with?

Answer: 1) Testing equipment: carbon monoxide detector, explosion-proof measuring instrument and toxic gas analyzer, etc.;

2) First aid equipment: oxygen respirators, ventilated gas masks, oxygen filling pumps and universal testers, automatic resuscitators, isolation self-rescuers, etc.

5. What components does the cyclone dust collector at the bottom of the gas furnace consist of?

Answer: 1) Ash pipe valve; 2) Ash accumulation tank

6. What issues should be paid attention to in the cyclone dust collector at the bottom of the gas furnace?

Answer: 1) The dust valve of the dust collector should be always open, and the water level of the dust tank should be ensured;

2) The dust should be cleaned several times per shift. When releasing the ash, the water level in the dust trough can be appropriately lowered, and then the ash pipe can be gently knocked down with a wooden hammer to cause the ash on the pipe wall to fall. During the ash removal process, the water level must be ensured to prevent the water seal from breaking through.

7. What is the working principle of electric focus capture?

Answer: The working principle of electric coke capture is that a metal wire is passed through high-voltage direct current and placed in the middle of the precipitation pole to form a strong magnetic field and a corona is formed around the wire. When the gas passes through, the dust and tar in the gas are ionized under the action of electric charges, move toward the charged metal wires and pipe walls, and lose their electric charge. Under the action of gravity, they fall to the bottom of the electric coke trap and flow out.

8. What are the functions of pressurizer and blower interlocking?

Answer: The function of the interlock between the pressurizer and the blower is that after the blower fails or automatically stops for other reasons, the pressurizer can also stop automatically to prevent the system from being sucked into negative pressure and causing danger.

9. What are the ancillary equipment of the gas generator?

Answer: The ancillary equipment of a gas generator generally refers to three types: check valve, steam drum, and bell valve. The reason why these three types of equipment are attached (indispensable) to the gas generator is that their functions are directly related to the operation of the generator, and they are devices that must be attached to the generator.

10. What are the water quality standards for softened water used in steam drum systems?

Answer: Water supply standard: suspended solids (mg/L)≤5. Total hardness (mmol/L)≤0.03, pH value≥7

Boiler water standard: dissolved solids<5000milligrams/Lift，total alkalinity：6-26millimole/Lift，relative alkalinity<0.2
