Shell boilers - Part 11: Acceptance tests

This Part of this European Standard specifies a concise procedure for conducting thermal performance tests, using the indirect (losses) procedure for boilers for steam or hot water. Test results are based on either the gross or net calorific value of the fuel.This concise procedure provides a convenient means for assessing boilers which thermodynamically simple, i.e. having a single major source of heat input and a simple circuit for water, steam or high temperature heat transfer fluid.NOTE 1 The use of the direct method is not advocated, because the estimated measuring error is three to four times greater than with the indirect method.NOTE 2 An acceptance test may be required:a) after the commissioning of new plant or after the recommissioning of modified plant in order to verify compliance with a specification or contractual obligation;b) whenever the user wishes to determine the current performance of the plant either on a route basis or due to change of load or other operating conditions or when a change of fuel or a modification to the plant is being considered;c) whenever the user wishes to check combustion conditions.Regular tests in accordance with this European Standard will enable boiler plant to be monitored in normal operation for opti-mum efficiency in the interests of fuel conservation.This procedure does not cover condensing boilers. The application of boilers, where heat is extracted from waste gases is specified in annex B.

Water-tube boilers and auxiliary installations - Part 15: Acceptance tests

This European Standard covers direct-fired steam and hot water generators, including the auxiliaries. For the purposes of this standard, steam and hot water generators are vessels and pipework systems in which:_ steam at a pressure higher than atmospheric pressure is generated for use external to the system;_ water is heated to a temperature higher than the saturation temperature at atmospheric pressure for use external to the system.A steam generator normally consists of the flue gas-heated evaporator, the superheater, the reheater, the feedwater heater, the air heater, the fuel heater, if any, and the fuel burning equipment.The term 'direct-fired' relates to equipment by means of which the chemical heat in the fuel of known composition is converted to sensible heat. Such equipment can involve stoker firing, fluidized-bed combustion or burner systems.The auxiliaries include the fuel feeders, the pulverizer, the FD (forced draught) fan, the ID (induced draught) fan, the facilities for removal of the refuse (combustion residues), the steam air heater, the main air heater, the fuel heater, if any, and the dust collector.

The quality of the steam produced is outside the scope of this standard.This Part of this European Standard aims to ensure that the boiler is able to be operated to minimize risk to personnel, the boiler and associated plant components located near it.NOTE This European Standard does not aim to achieve optimum economic operation. For certain purposes, it will be more appropriate to optimize the chemical characteristics in order to:- increase the thermal efficiency;- increase the availability and reliability of the plant;- increase steam purity;- reduce the maintenance costs - repair, chemical cleaning, etc.This Part of this European Standard sets out minimum requirements for the specific types of water to reduce the risk of corrosion, sludge precipitation or formation of deposits which may lead to any damage or other operating problems.NOTE This Part of this European Standard has been prepared on the assumption that the user of this European Standard possesses a sufficient knowledge of the construction and operation of the boiler as well as an adequate appreciation of water and steam chemistry.
