Completion of definitions and units conversion concerning some | Contents |
TABLE OF PRODUCTS - ITEMS
1st row
- Product´s title
- Energy code - is identical with the code used for products of the industrial statistics department no. 321 CSO relating to statistical reports
- Prům P 2 - 12 and Prům P 3 - 12 valid for the period 1985-1993.
- Specific unit - S P U - physical specific unit for a product´s production (t, m3, th. m2, th. m3, m3 a.a = m3 absolute alcohol etc.)
- Code of industry 95
2nd row: Production
- - Total annual production of a product measured in specific physical unit SPU.
3rd and 4th row: Consumption of electricity
- Total consumption - Total annual electricity consumption (MWh)
- Specific consumption - eg. total consumption/production; calculated in kWh/SPU
5th and 6th row: Consumption of heat
- Total consumption - Total annual consumption of heat (GJ)
- Specific consumption - eg. total consumption/production (GJ/SPU)
7th and 8th row: Consumption of fuels
- Overall consumption - Total annual consumption of fuels (GJ)
- Specific consumption - eg. total consumption/production (GJ/SPU)
9th and 10th row: Occurence of secondary energy sources
- Emergence of energetically utilizable waste heat arising during production process, total (/GJ)
- Emergence of directly energetically utilizable secondary fuels arising during production process, total (GJ) - (for instance top gas or nitrogen rich gas, biogas, combustible wastes etc.)
11th and 12th row: Consumption of energy, total energy consuption
- Total consumption (total) - total annual energy consumption (GJ)
Explanation: SPU - Specific Physical Unit
Comment: Items relating to secondary energy sources were surveyed till 1989 year
Explanations concerning definitions and conversions of units with some items (bricks, roofings and fabrics) are cited on page 31.
Guiding tables for processing, eg.
Table 1: - Consumption of fuels, heat and electricity for the production of selected products - 2003 year
Table 2: - Specific consumption of fuels, heat and electricity for the production of selected products - 2003 year are shown on pages 87 and 88.
Completion of definitions and new calculations of units with some items
Bricks:
Brick unit: a brick of size 25 x 12 x 6,5 cm
1000 c.j. = 1,95 m3
Normal-sized brick = a brick of size 29 x 14 x 6,5 cm (= 1,3 c.j.)
1000 pcs. of normal-sized bricks = 2,639 m3
White brick = a brick of size 24 x 12,5 x 6,5 cm (1 c.j.)
1000 pcs. white bricks = 1,95 m3
Perforated bricks:
Perforated bricks of size 36,5 x 24,5 x 14,5 cm (=6,65 c.j.)
1000 pcs. perforated bricks = 12,966 m3
Perforated bricks II. of size 49 x 24,5 x 14 cm (= 8, 62 c.j.)
1000 pcs. perforated brick II. = 16, 807 m3
Cinder concrete bricks:
Cinder concrete bricks of size 38 x 25 x 22 cm (10,72 c.j.)
1000 pcs. cinder concrete bricks = 20,9 m3
Cinder concrete bricks II. of size 38 x 30 x 20 cm (= 11,7 c.j.)
1000 pcs. cinder concrete bricks II. = 22,8 m3
Burnt roofing:
HOLLAND TYPE:
Maximal surface mass = 45 kg/m2
Number of pcs/m2 = 14,4 pcs.
Unit mass = 3,1 kg/pcs.
BOBROVKA TYPE
Maximal surface mass = 70 kg/m2
Number of pieces/m2 = is between 36and 38 pcs.
Average specific mass is equal to approximately 1,8 kg/pcs
Fabrics:
Fabrics of all kinds are manufactured in widths from 0,6 m up to 1,6 m.
The most manufactured sizes are 0,9 m, 1,2 m and 1,3 m.
Conversion of usual metres on m2: m2 = bm x width (in meters)
The similar procedure is used , for example, at conversion of flat drawn glass of known thickness from square meters to cubic ones and similarly.
