Abstract
Disclosed is a parallel operation of coal gas production system to provide syngas and fuel gas for producing methanol and synthetic ammonia and generating electricity. The method arranges one or more briquette gasifiers in parallel connection with a powder coal gasifier, on one hand, reducing the economic loss by the shutdown of the whole product line caused by the troubleshooting of the coal gas production system as well as the pollution to the environment and potential safety hazard, and on the other hand, guaranteeing a continuous producing and a large investment saving by a reserve of continuous gas making of briquette which also uses powder coal as the raw material.
Description
Technical field
The present invention relates to a kind of coal gas producing system operation method, a kind of especially coal gas producing system parallel-connected operation method that adopts the two-shipper parallel connection provides synthetic gas and fuel gas for producing methyl alcohol and synthetic ammonia, generating.
Background technology
Present gasifying powder coal device because the cost of investment height, is not set up standby vapourizing furnace, and with heavy oil gasification when coal gasification is undesired as a supplement.But as standby heavy oil gasification device not only raw materials cost, energy consumption height, and the heating reduction time is long, and the heavy oil gasification device can not in time be driven when the coal gasification apparatus scram, causes the total system full cut-off, has a strong impact on production and environment, safety.In addition, maintenance or parking phenomenon often appear in gasifying powder coal device operation conditions instability, and the cycle of operation is short, the maintenance cost costliness, and the production fluctuation is big.
Summary of the invention
Purpose of the present invention promptly provides a kind of coal gas producing system continous-stable operation that makes, and has both avoided the pollution of gas to environment, has obtained good economic benefits, the coal gas producing system parallel-connected operation method that reduces cost again.
The object of the present invention is achieved like this: a kind of coal gas producing system parallel-connected operation method, and powder coal gasification furnace operation system gas, it is standby to dispose the type coal gasification stove in parallel with powder coal gasification furnace.The type coal gasification stove of configuration can be more than two or two.The type coal gasification stove specification of configuration is identical.
The method of coal gas producing system parallel-connected operation provided by the present invention, by adopting the method for configuration one or more type coal gasification stove in parallel with powder coal gasification furnace, saved on the one hand because of powder gas maked coal system breaks down and overhauled the financial loss that causes full bar production line to stop and bring, reduced pollution and the potential safety hazard brought because of reasons such as parkings simultaneously environment; Be that the moulded coal of raw material is made gas continuously and done standbyly with fine coal by adopting same on the other hand, guaranteed the continuity of producing, saved investment again significantly.
Embodiment
Set up 1#, 2# two cover synthetic gas system gas systems, 1# powder gas maked coal system (shell stove) operation, 2# type gas maked coal system is standby with six bench-type coal gasifiers.
When shell vapourizing furnace (1000t/d) breaks down and can't normally make gas, open one or more standby 3300 type coal gasification stoves according to producing needs, stoppage in transit shell vapourizing furnace guarantees to produce operation continuously, tremendous economic loss and waste discharge and the equipment corrosion avoiding stopping and cause.Standby type gas maked coal system reduces investment outlay 2.5 hundred million yuan than standby shell vapourizing furnace simultaneously.
Claims (3)
1. coal gas producing system parallel-connected operation method is characterized in that: powder coal gasification furnace operation system gas, it is standby to dispose the type coal gasification stove in parallel with powder coal gasification furnace.
2. coal gas producing system parallel-connected operation method according to claim 1 is characterized in that: the type coal gasification stove of configuration can be more than two or two.
3. coal gas producing system parallel-connected operation method according to claim 1 and 2 is characterized in that: the type coal gasification stove specification of configuration is identical.
