scope:

This Code applies to gasifiers that convert liquid or solid feedstock into syngas by means of an oxygen- or air-blown gasification process. It can be used to measure the performance of a gasifier in its normal operating condition, with all equipment in new condition.

The Code addresses the boundaries of the gasification block and the principal streams moving through the gasification block that significantly affect its thermal performance (see Figure 3-2.2-1). This Code provides methods to measure the quality and quantity of product (e.g., syngas) and by-product (e.g., slag and ash), feedstock consumption rates, oxidant consumption, steam consumption and production, water consumption, inert gas consumption, and power use. The Code includes methods for calculating cold gas efficiency and carbon conversion as examples, but these calculations are not within the scope of this Code.

Gasifier performance tests conducted in accordance with this Code shall meet the following conditions:

(a) A means shall be available for determining, through direct or indirect measurement, all electric power feeds entering or exiting the test boundary.

(b) A means shall be available for determining, through direct or indirect measurement, the composition and condition of all pressurized flows entering or leaving the test boundary.

(c) A means shall be available for determining, through direct or indirect measurement, all parameters required to correct test results to a base reference condition.

(d) The test uncertainties shall be less than or equal to the specified uncertainty limits.

Tests addressing other performance-related issues are outside the scope of this Code. These include but are not limited to the following:

(a) emissions tests

(b) operational demonstration tests pertaining to non-steady state or off-design conditions

(c) reliability tests conducted over periods of time beyond the required testing period
