Abstract
A system by which a supplier of wet steam may allocate and measure the mass flow rate and quality of steam delivered to a demand user and one or more secondary users with the wet steam delivered to each user being measured for purposes of billing. Pressure regulator means between the demand customer and the secondary customers responsive to pressure changes caused by the amount of steam going to the demand customer. The demand customer thus being able to take from 0 to 100% of the steam generator output with the remaining steam being allocated to the secondary customers.
Claims5
A system for automatically controlling the quantity of wet steam delivered to a plurality of customers from a single steam source, said system comprising:
- steam generating means having an inlet connected to a feed water source and an outlet:
- means connected to said steam generating outlet to measure the steam quality from said steam generating means;
- a demand customer connected to said outlet of said steam generating means;
- a plurality of secondary customers connected in parallel;
- pressure regulator means connected between said demand customer and said secondary customers and configured to maintain constant discharge pressure to the demand customer;
- and
- steam flow measurement means to simultaneously measure mass flow rate and steam quality of two phase steam and connected between said pressure regulator and each secondary customer to determine the quality and quantity of wet steam delivered to each respective secondary customer.
