摘要： PROBLEM TO BE SOLVED: To provide a fluid mixer which reliably mixes fluids in the state of low pressure loss and discharges the fluids as a uniformly mixed fluid even when the fluids are inhomogeneous in composition, temperature and/or concentration. SOLUTION: The homogeneity of an outlet fluid 6 of this fluid mixer 7 is achieved by disposing short pipes 5 respectively on fluid emitting parts 3a-3d which are disposed on a fluid dividing member 2. The fluids 1 which flow out of the short pipes 5 directly collide against or interfere with one another and generate a flow region of violent turbulence in the neighborhood. Therefore, even when the fluids 1 are inhomogeneous in composition, temperature and/or concentration, the fluids are almost uniformly mixed by being subjected to a passage through the flow region of violent turbulence generated by the fluid dividing member 2.

摘要： PROBLEM TO BE SOLVED: To provide an operation method of a hydrolysis separator for generating ammonia from urea which is capable of timely retaining the production amount of ammonia necessary for stack-gas denitrification to a suitable amount when ammonia is produced using steam for heating from a urea water. SOLUTION: At the starting time of the hydrolysis separator which generates ammonia gas used as a reducing agent of the stack-gas denitrification equipment by hydrolysis of a urea water, the constant pressure operation where the pressure within the hydrolysis separator is kept constant even to the temperature elevation of the hydrolysis separator is performed at the initiation time of injection of the ammonia gas, and then the operation method is switched to the sliding pressure operation where the pressure is also elevated in accordance with the temperature elevation of the hydrolysis separator. At the switching point from the constant pressure operation to the sliding pressure operation, the temperature of the hydrolysis separator in the constant pressure operation is set to the temperature of the sliding pressure operation or more at the same pressure.
