Water .
The charge in heat recovery coke ovens is heated from the top mainly by radiation from the crown and partially burned raw-gas of the upper-oven. The share of convection is small and the convective heat transfer coefficients are typically not larger than 20 W/m 2 K. Also the ceiling of the sole-flue is mainly heated by radiation.

• Heat Recovery Coke Oven: horizontal oven type, and vertical oven type According to the requirement and coal feedings of customers, ACRE can supply top-charging coke oven batteries with different oven height and production capacities, complete package of coke-making equipment and coke oven machines.
Commercial coke is generally made in one of two ways: (1) By-Product Coking and (2) Non-Recovery/Heat Recovery Coking. A majority of the coke produced in the United States comes from By-Product Coking, where the coal is carbonized in large ovens and the off-gas is collected and processed to recover various carbon-based by-products, .
As an engineering innovation, the FDSCoke Plant will not contain valves between the coke ovens and the heat recovery steam generator ("HRSG") associated with each coke oven process module. This innovation will result in superior environmental performance and reduced operation and maintenance costs.
Coke batteries are of the nonrecovery type; some ovens are equipped with heat recovery. Coking mechanism should be different from what is known from normal coking operation with coal. Pitch softens at much lower temperatures than coking coals.
SunCoke Energy's heat-recovery cokemaking process converts waste heat into steam and electricity, which we can sell to our customers. A typical heat-recovery facility that we design and operate to produce 1.1 million tons of coke per year can generate more than 90 megawatts of electric power per hour.
It also increases the yield in the coke plant and may help improve the performance in heat recovery systems. Emissions reduction is unlikely. Investment and operational costs are reported to be reduced, due to reduced oven compartments and ability to use lower grade coal.
