1 General
1.1 Field of application
This standard applies to central heating gas-fired boilers of type B11BS, hereafter referred to as
“boilers”:
- fitted with low pressure atmospheric burners
- that use gases corresponding to the three gas families
- that have a nominal heat input not exceeding 70 kW
- where the temperature of the heat carrier does not exceed 95 °C during normal operation;
- where the maximum water-side operating pressure does not exceed 6 MPa
This standard doesn’t apply to boilers:
- intended to be installed in the open
- having multiple heating units with a single draught diverter;
- with fan burners;
- of the condensing type;
- intended to be connected to a common flue having mechanical extraction;
- fitted with manual or automatic means of adjusting the air supply and/or adjusting the evacuation
of the combustion products;
- of the combination type (central heating and domestic hot water production)
1.2 Normative references
In this standard references to following standards are used:
GOST 6357-81 Basic norms of interchangeability. Cylindrical pipe thread.
GOST 14254-96 (МEК 529-89) Degrees of protection provided by enclosures (IP code)
GOST 16093-81 the Basic norms of interchangeability. Metric screw thread. Tolerances. Plantings
with a clearance
GOST 24705-81 the Basic norms of interchangeability. Metric screw thread. Principal dimensions
GOST 27570.0-87 (МЭК 335-1-76) Safety of household and similar electrical appliances. General
requirements and test methods
GOST R 51318.14.1-99 (SISPR 14-1-93) Electromagnetic compatibility of technical means. Industrial
radiointerferences from household appliances, electrical tools and similar devices. Norms and test
methods
1.3 Definitions and symbols
For the purposes of this standard, the following definitions apply:
1.3.1 Test specifications
1.3.1.1 reference conditions: Environment temperature of 15 °С, atmospheric pressure 101,3 кPа.
1.3.1.2 standard conditions: Environment temperature 20 °С, atmospheric pressure 101,3 кPа.
1.3.2 Gases
1.3.2.1 Test gases (gases): Gases used to check operating characteristics of boilers using combustible
gases. Test gases subdivide on reference and limit gases:
- Reference gas: Test gas with set chemical composition, its parameters correspond to the most
abundant gases in gas supply, with which the boilers operate in nominal conditions.
- Limit gas: Test gas with set chemical composition, corresponding to extreme variation in the
characteristics of the gases capable of being used.
1.3.2.2 Calorific value QP : the quantity of heat produced by the combustion of unit volume or mass of
gas.
Units:
- Either megajoules per cubic metre of dry gas brought to reference conditions (МJ/m3);
- Or megajoules per kilogram of dry gas (MJ/kg).
Two types of calorific value are identified:
- Gross calorific value P
QB : the quantity of heat produced at complete combustion of a unit volume or
a mass unit of dry gas under normal conditions, water produced by combustion is taken to be condensed.
- Net calorific value PH
Q : the quantity of heat produced at complete combustion of a unit volume or a
mass unit of dry gas under normal conditions, water produced by combustion is taken to be in the vapour
state.
In this standard apply only the net calorific value.
1.3.2.3 Relative density ρ : the Ratio of the masses of equal volumes of dry gas and dry air under the
same conditions of temperature and pressure.
1.3.2.4 Wobbe index W: The ratio of the calorific value of a gas per unit volume and the square root of
its relative density under the same reference conditions. It characterizes a constancy of the heat flow
gained at gas. Wobbe index is said to be gross (Ws) or net (Wi) according to whether the calorific value
used is the gross or net calorific value. The Wobbe indices are expressed in megajoules per cubic metre
(МJ/м3).
1.3.2.5 Gas pressure: Static pressure of the moving gas, relative to the atmospheric pressure. Units:
kilopascal (кPа).
Pressure types:
Test pressure: Gas pressure used to check the operational characteristics of boilers Test pressures
comprise of nominal and limit pressures:
1) nominal pressure pn: the Static gas pressure corresponding to the boiler's nominal heat input when
supplied with the corresponding reference gas
2) limit pressure: Pressures representative of the extreme conditions of the boilers.
symbols: pmax - maximum pressure; pmin - minimum pressure.
difference that exists between the Wobbe indices within a single gas family or group:
- the highest pressure corresponds only to the low Wobbe index gases,
- the lowest pressure corresponds to the high Wobbe index gases.
1.3.3 Constituent parts of the boiler
1.3.3.1 Gas supply:
- Gas inlet connection: the Part of the boiler intended to e connected to the gas supply.
- Gas circuit: Parts of the boiler that carry or contain the combustible gas between the boiler gas inlet
connection and the burner(s).
- Restrictor: a device with one or more orifices, which is placed in the as circuit so as to create a
pressure drop and thus bring the gas pressure at the burner to a predetermined value for a given supply
pressure and given rate.
- Injector: a component that admits gas into the burner
- Gas rate adjuster: a component allowing the gas rate of the burner to be brought to a predetermined
value according to the supply conditions. The action of operating this component is called “adjustment of
the gas rate”
- Range-rating device: a component intended to be used to adjust the nominal heat input of the boiler,
within the range of maximum and minimum heat inputs stated by the manufacturer, to suit the actual heat
requirements of the installation
- Primary aeration adjuster: a component enabling aeration of a burner to be set to the desired value
according to the supply conditions.
The action of operating this component is called “primary aeration adjustment”
a) main burner: a burner in which one all fuel or its main part.
b) ignition device: device intended for an ignition of the burner.
c) manual ignition device: a device by means of which the burner is ignited following manual
intervention
d) automatic ignition device: an automatic device which ignites the pilot burner or the main burner
directly
e) pilot burner: a burner intended to ignite the main burner.
Types of pilot burners:
1) permanent pilot burner: The pilot burner operates continuously throughout the whole period that
the boiler is in use
2) intermittent pilot burner: Pilot burner that is ignited before and extinguished at the same time as
the main burner.
3) alternating pilot burner: A pilot burner that is extinguished as soon as ignition of the main burner
is effected. It re-ignites at the main burner flame just before the latter goes out.
4) interrupted pilot burner: A pilot burner that operates only during the ignition sequence.
1.3.3.2 Combustion products circuit
Circuit consists in the combustion chamber, the heat exchanger and the circuit permitting evacuation
of the combustion products to the flue, up to and including the flue outlet, combustion products discharge
safety device and draught diverter:
- combustion chamber: an enclosure inside which combustion of the air-gas mixture takes place
- flue outlet: the part of the boiler through which the combustion products are evacuated to the flue
system
- draught diverter: a device, placed in the combustion products circuit of a boiler, that is intended
to maintain the quality of combustion within certain limits and to keep the combustion stable under
certain conditions of updraught and down draught
- combustion products discharge safety device: a device that at least causes safety shutdown of the
main burner when there is an unacceptable spillage of combustion products at the draught diverter
1.3.3.3 Adjustment devices, controls and guards:
- pressure regulator: A device which maintains the downstream pressure constant to within fixed
limits independent of variations, within a given range, of the upstream pressure and the gas rate. |
