Shandong horizontal natural gas boiler manufacturer Zhongjie Equipment provides high-quality and excellent service to customers

Description :

　　（1） Commonly used heating boilers are divided into two categories according to the heating medium:

　　1. Steam boiler;

　　2. Hot water boiler (projects with only heating heat load generally use hot water boilers as heat sources).

　　（2） Commonly used heating boilers are divided into four categories according to the type of fuel:

　　1. Coal fired boilers; 2. Gas boilers; 3. Oil fired boiler; 4. Electric boiler.

　　（3） For example: Model DZL64-1.6/130/70AII

　　DZ - Single drum vertical type; L - Chain grate;

　　64- Rated heating capacity Q=64MW; 1.6- Medium outlet pressure 1.6MP;

　　130/70- rated supply and return water temperature of 130 ℃/70 ℃;

　　AII - The fuel type is II bituminous coal.

　　（4） Gas fired boiler

　　1. Pressure gas boiler (p ≥ 0.1MPa);

　　2. Atmospheric pressure gas boiler (open type atmospheric pressure);

　　3. Vacuum gas boiler (p<0.1MPa negative pressure boiler).

　　Atmospheric pressure boilers and vacuum boilers are not subject to inspection by departments such as the Special Equipment Association, and do not require safety inspections by the Special Equipment Association when installed in basements.

　　Construction Procedure of Heating Engineering

　　1、 Heating planning

　　（1） The purpose and role of formulating heating planning

　　By conducting heating planning for local heating areas, guide the orderly engineering design and construction of local heating projects.

　　2、 Feasibility Study Report

　　（1） The purpose and role of preparing a feasibility study report

　　1. Determine the reasonable construction scale, process plan, and economically feasible investment estimate for the heating project through detailed research and analysis.

　　2. As a foundational document for submitting project proposals.

　　3、 Preliminary design

　　（1） Purpose and role of preparing preliminary design

　　1. As a technical support document for conducting major equipment and system bidding.

　　2. As a technical document for determining the planning permit.

　　3. As a foundational document for submitting and reviewing project estimates.

　　4、 Construction drawing design

　　（1） The purpose and creation of construction drawing design

　　1. For the purpose of project construction and equipment installation

　　2. Used for reporting fire safety, civil air defense, design review, construction, and other purposes.

　　5、 Boiler room construction

　　（1） Project procurement

　　（2） Civil construction

　　（3） Installation of process equipment:

　　Equipment foundation review → installation of main equipment → installation of auxiliary equipment → production of non-standard equipment → installation of process pipelines → inspection of valves and accessories → installation of air and smoke systems → non-destructive testing of pipelines → system pressure testing → anti-corrosion, insulation, and labeling of pipeline equipment.

　　（4） Electrical installation

　　（5） Thermal automatic control installation

　　（6） System trial operation:

　　1. Oven boiling; 2. System joint trial debugging.

　　6、 Inspection procedures after completion of construction:

　　1. Apply for environmental protection acceptance to the Environmental Protection Bureau

　　2. Apply for fire safety inspection to the fire department

　　3. Apply for water quality acceptance to the epidemic prevention station

　　4. Apply for inspection to the Electric Power Construction Office

　　5. Apply for inspection to the Construction Committee

　　6. Apply for inspection to the Quality Supervision Bureau

　　7. Apply for inspection to the public quality supervision station

　　8. Apply for inspection to the Urban and Rural Construction Archives

　　9. Apply for inspection to the Meteorological Bureau

　　On the basis of completing the above-mentioned application for acceptance and obtaining approval, the four party acceptance and completion acceptance of the owner unit, construction unit, supervision unit, and design unit can be carried out.
