Liqnite Byproduct Business 

     EGAT produces and sells three types of lignite byproducts from the lignite-fired power generation of Mae Moh Power Plant in Lampang province, including:

  • Lignite Fly Ash
  • Lignite bottom ash
  • Synthetic gypsum

 

Lignite Fly Ash

Quality
EGAT’s lignite fly ash is of Class C (ASTM C 618) type, with specific gravity of 2.00-2.60 and containing free lime of less than 3% and sulfur trioxide (SO3) of less than 5%.

Prior to delivery to customers, our fly ash products are under quality control system to ensure the product standard quality. We also help facilitate our customers in obtaining property check from the Department of Industrial Works as well as transport licensing. Customers can always be assured of our prompt and efficient delivery service and the standard quality of EGAT’s lignite fly ash products.

Uses and benefits

EGAT’s lignite fly ash products have good pozzolan or binding properties and are therefore an excellent choice for construction material to substitute Portland Cement Type 1 at a much cheaper cost. Our fly ash products can also be used as filler for the ready-mixed concrete production, enhancing strength and durability of concrete. Our lignite fly ash products also help save energy used during the concrete mixing process as the spherical and fine shape of the fly ash grains contributes to low friction between particles.

Lignite Bottom Ash

Quality

EGAT’s lignite bottom ash is of black color with its particle size of 0.1-10 mm. and specific gravity of 3-5, and the properties of water and air permeability.

Uses and benefits

EGAT’s researches and studies on the application of lignite bottom ash from Mae Moh Power Plants have indicated the Mae Moh lignite bottom ash offers excellent potential for use as an aggregate in road construction or concrete as well in the production of concrete blocks for various construction works. Bottom ash can also be used for agricultural purposes.

Synthetic Gypsum

Quality

EGAT’s syhthetic gypsum product is of yellow color with over 90% of gypsum purity (CaSO4.2H2O) and 10-20% humidity.

Uses and benefits

EGAT’s synthetic gypsum from Mae Moh Power Plant offers excellent potential use as raw material for the production of cement and fiber cement. Our synthetic gypsum can help slow the setting of cement and thus contributes to the higher strength and durability of cement.

Synthetic gypsum can also be used as a raw material in producing organic fertilizer to help improve soil quality and contribute to the fast growth of cash crops like rice, sugar cane, soy beans, corn, tomato, cucumber and etc. It also helps improve water absorption of the plant roots. Synthetic gypsum can be applied with all types of soil, either the soils affected by drought or flood.
