Products Description
(1) Drawing design is not reviewed in detail, key parts and important links are not reasonably designed, design omissions, and design optimization recommendations.
(2) Process handover orders signed by all parties not completed before construction, and temporary parts affecting furnace lining construction not removed in time.
(3)The elevation position and installation requirements of the boiler heating surface, cyclone separator related pins, brackets, anchors, door holes, etc. were not checked and corrected in detail, and some of the pins and anchors were not welded firmly.
(4) Insufficient supply of water, electricity and transportation energy at the site, and no moisture-proof, water-proof and high-temperature-proof facilities.
Products Specifications
1. Optimize the design.
Before the construction of boiler lining, the professional construction team should be organized in a timely manner to review the drawings and optimize the design of the key parts.
Construction parts: furnace outlet top, separator inlet flue top, separator top, separator cone; original drawings: wear-resistant refractory plastic, optimized design: chrome steel jade can be plastic, optimization of the difference between the former: to improve the wear resistance of the material.
2 Precautions after installation.
Steel structure, heated surface, furnace wall metal parts and other equipment installation is completed (including the manufacturing plant and the site weld tightness check, wind and water pressure test), acceptance, process handover procedures in place. Furnace wall construction has an impact or construction after the removal of temporary metal components (such as reinforcement, support, etc.) should be removed to avoid high-temperature metal components expansion stress on the wear-resistant refractory casting layer caused by local damage. The boiler heating surface, cyclone separator related pins, brackets, anchors, door holes and other elevation position and installation requirements for checking and proofreading, carefully check whether the metal anchors are welded firmly, the arrangement of the spacing is in line with the requirements, not up to the requirements of the requirements are required to make up for the weld, to increase the number of pins, until it reaches the quality requirements.
3.Construction site conditions
The total power supply receives the power box of each layer of the boiler, and 10m³ water storage tank is set on the top of the boiler to ensure uninterrupted water supply during the pouring construction. All construction materials are transported to the combination field by container. The road is smooth to ensure that the transportation vehicles reach the elevator entrance from the combination yard. Boiler separator outlet flue, separator inlet flue, return valve, boiler 12 floors are equipped with 4 stacking and mixing processing places, using elevator, trolley, 0.5 winch, to ensure the continuous supply of construction materials.
