Hydrazine - Infogalactic: the planetary knowledge core

Hydrazine is an inorganic compound with the chemical formula H 2 NNH 2 (also written N 2 H 4).It is a colorless flammable liquid with an ammonia-like odor.Hydrazine is highly toxic and dangerously unstable unless handled in solution. As of 2000, approximately 120,000 tons of hydrazine hydrate (corresponding to a 64% solution of hydrazine in water by weight) were manufactured worldwide per year.

BOILERS | Energy-Models.com

Fire tube or "fire in tube" boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. (Refer Figure 2.2). Fire tube boilers, typically have a lower initial cost, are more fuel efficient and easier to operate, but they are limited generally to capacities of 25 tons/hr and pressures of 17.5 kg/cm 2.
