The production technology of honeycomb briquettes that can be ignited with a match

▲It takes 2 minutes to start the fire quickly and the flame is one foot long ▲It takes 12 minutes to boil a pot of water with strong firepower

The flammable honeycomb briquettes have the following characteristics:

① Briquettes can be ignited with a match. It breaks the traditional combustion method (burning from top to bottom), and the flame reaches one foot high in 2 minutes after ignition;

② Fierce firepower, large flame, and blue color The flame is high and long-lasting, and the furnace mouth temperature is about 800 degrees (the same as the gas stove mouth temperature);

③ Save coal, no need to seal the furnace, it can be burned and lit like liquefied gas, and it can be discharged at one time Put in two pieces of coal and it can burn for more than 120 minutes. The firepower is comparable to that of liquefied gas (it can continuously cook three kilograms of rice, cook 5-8 dishes, one soup and one pot of water);

④ The burning stove does not burn It is a multi-purpose fuel that combines the advantages of coal, gas and liquefied gas;

⑤The cost is low. Calculated at 250 yuan per ton of raw coal, the cost of each piece of coal (100×70) mm is no more than 8 cents. The finished product will not fail after long-term storage. It is safe to store and is not an flammable or explosive item;

⑥Main raw materials: ordinary coal (including: anthracite, inferior coal, loess and a small amount of chemical raw materials and auxiliary raw materials, which can be purchased in all counties and cities).

To produce briquettes, the equipment investment is 1,800 yuan (small crusher, mixer); it can also be made by hand, with one set of molds per person producing 1,000-1,500 yuan per day (mechanical production is also possible), and the working capital is about 1,000 yuan. , the market price is generally 0.20-0.25 yuan/block. If you set up a small factory with 10 people, the annual profit will be about 200,000 yuan.

There are many formulas: for example, use 25% strontium nitrate, 9% potassium peroxylate, 5% saltpeter, plus carbon powder, 2% 3% cement powder, 3% saltpeter lime, 5% tannic acid, and 3% organic waterproof coating as the ignition layer. Another example is using barium sulfate (oxygen promoter) 30, potassium nitrate (oxygen promoter) 1.7, potassium permanganate (catalyst) 0.9, wood carbon powder (low flash point carbon-based material) 17, carbonized sawdust (low flash point carbon-based material) Materials) 13. Anthracite (high carbon-based material) 30. Calcium chloride (purifying agent, also known as lime powder) 2. Iron trioxide (purifying agent) 1.7, adhesives, etc. as ignition agents.

Formula 1

Potassium nitrate: 0.015 kg Coal: 0.5 kg Sawdust: 0.235 kg Quicklime: 0.15 kg Loess: 0.1 kg Paraffin: appropriate amount (Added later) ]3

First mix the above five raw materials and add water to make honeycomb briquettes. Dry them thoroughly and set aside. Then melt the paraffin in a pot and dip it in the pot with dry honeycomb briquettes. Formulation

Recipe 2

1. 20% anthracite powder, 30% clay, 45% sawdust, add an appropriate amount of water, stir evenly and make honeycomb briquettes as usual. However, it is required that there should be a small depression in the middle of the upper plane of the briquettes;

2. In a glass or porcelain container, mix hexamethylenetetramine with a small amount of water into a paste, and then use a small spoon to Add 1.5 grams of each piece of coal into the small cavity, and then dry it in the sun or air;

3. Paste a small piece of paper on the small cavity of the honeycomb briquette, and clean six of them Methyltetramine plays a protective and sealing role;

4. Use a match to light a small piece of paper to ignite the hexamethylenetetramine, and then ignite the entire briquettes
