Information
Horizontal (condensing) fuel oil (gas) steam boilers need to be tested for energy efficiency when they are newly installed, or when they are recently renovated, to ensure the normal use of the boiler and to ensure the efficiency of the boiler. So in Dongguan, how should the horizontal (condensing) fuel (gas) steam boiler energy efficiency test be handled, and where?
 
The editor here introduces you to the energy efficiency testing service guide for horizontal (condensing) fuel oil (gas) steam boilers.
 
1. Scope of acceptance
 
1. Newly installed boilers; 2. Boilers that have been recently remodeled; 3. In-use boilers.
 
 
2. Conditions
 
1. For the energy efficiency test of newly installed boilers, the following information is required (not required for retrofit or boilers in use):
 
(1) Boiler design specification (including design output range, design fuel requirements and fuel classification); (2) boiler general plan;
 
(3) Boiler thermal calculation book (including boiler design load range calculation thermal efficiency curve);
 
(4) Calculation of boiler flue gas resistance;
 
(5) Calculation of boiler water resistance;
 
(6) Instructions for use of the boiler;
 
(7) Models of fuel oil and gas burners used.
 
2. Boilers that need to be modified or in use must provide:
 
(1) Boiler use certificate;
 
(2) Certificate of boiler product quality;
 
(3) Transform the thermal calculation book (if any).
 
3. The tested boiler and auxiliary system should meet the following conditions:
 
(1) The boiler can operate safely and stably within the design output and parameters allowable range;
 
(2) The auxiliary machine system should match the boiler output and operate normally (there should be no running, running, dripping or leakage);
 
(3) The fuel used in the test should meet the design coal requirements;
 
(4) The boiler and auxiliary system should be able to meet the layout requirements of each measuring point in the test program
 
4. The tested boiler should reach a stable thermal condition before the test, that is, the main thermal parameters of the boiler fluctuate within a range of not more than 5%, and the average value does not change with time. The time required to stabilize the thermal conditions is:
 
(1) For shell-type oil-fired and gas-fired boilers without brick walls (fast and assembled), no less than 2h, and coal-fired boilers no less than 4h
 
(2) No less than 8h for light boilers;
 
(3) Not less than 24h for heavy-duty boilers.
 
 
3. Procedures
 
(1) Appointment test acceptance
 
The boiler user unit shall go to the business window of Dongguan Branch of Guangdong Special Equipment Inspection Institute or the business window of the chemical supervision and inspection room to receive the "Entry Acceptance Form for Industrial Boiler Energy Efficiency Test".
 
(2) Acceptance procedures
 
① The relevant person in charge of the boiler use unit (or installation company) holds the "Entry Acceptance Form for Energy Efficiency Testing of Industrial Boilers" to sign the acceptance form with the person in charge of energy efficiency testing in the chemical supervision and inspection room, and then goes through the payment procedures at the business window of our hospital.
 
②After the user unit is put into production and the boiler is in normal operation, the boiler user unit (or installation company) notifies the relevant personnel of the Chemical Supervision and Inspection Laboratory of our hospital to make an appointment for the energy efficiency test time.
 
(3) Confirmation of on-site test conditions
 
Before the test, the relevant personnel of the test go to the boiler user unit to check the boiler operation status, and make preparations before the test. If necessary, write a test outline.
 
 
4. Payment
 
(1) The test application unit holds the UnionPay card and swipes to pay at the charge window of our branch;
 
(2) Transfer (for details, please refer to the acceptance slip).
 
 
V. Receiving the report
 
After the test work is completed, the report will be received at the report issuance window of the Chemical Supervision and Inspection Laboratory of our hospital with the "Entry Acceptance Form for Industrial Boiler Energy Efficiency Test" after 15 working days.
