The electric igniter ignition: ignition rate 20 times 16 times more light, not 2 consecutive failure, no explosion. Combustion stability: the rated pressure, the burner flame uniform, stable, should not even flame, no temper, no flame and yellow flame. Durability: gas cock valve after 15000 times of use, shall be in accordance with the gas passage air tightness requirements. The electric igniter is used for 15000 times, should be consistent with the ignition performance requirements. The valve body and an electric igniter life should produce products factory inspection certificate. Structure: the wind regulating plate valve and gas stove should be flexible, easy to operate, and the position should not be free of loose. Valve is "on" and "off" should be obvious Chinese signs and directions. The pot support biogas stove should be able to stably support the cooking utensils, when using the movable bracket, regulation should be convenient, flexible and convenient replacement. Put 98.1N in the pot bracket (10kgf) net load, should not be deformed or damaged. The stove surface load test, deflection range surface center should be 5mm. Material requirements: household stove burner material requirements with cast iron or stainless steel, the other material is not allowed; pan bracket material requirements by enamel, or cast iron, the service life should be at least 2 years; liquid bearing disc material requirements by enamel or stainless steel; beam material used should be made of stainless steel; gas conduit should use galvanized iron pipe, tube spring jacket plus length 5cm. 2, the thickness range surface should be made of stainless steel, material: (0.40 ± 0.01) mm. 3, the methane gas pipe, pipe fittings technical indicators based on agricultural industry standard "rural household methane gas transmission system in first parts: plastic pipe" (NY/T1496.1-2007) and "rural household methane gas transmission system in second parts: plastic pipe fittings" (NY/T1496.2-2007), clinch a deal the supplier will provide the test content to at least meet the above two standards project the testing report. 4, the material for the special material for PE pipeline. The pipe surface should be smooth, bubbles, cracks, peeling and severe cold spots, obvious uneven color, discoloration decomposition is not permitted. 5, the methane purifier technology should be consistent with the agricultural industry standard "methane pressure meter (NY/T858-2004)", "gas desulfurization devices" (NY/T859-2004) and "rural methane gas system in third parts: plastic switch" (NY/T1496.3-2007) regulations. The marsh gas purifier for housing for the integration of cleaner cartridge, including the pressure gauge, a desulfurizing device and a flow control valve, its main function is the system pressure display, biogas digesters in the removal of hydrogen sulfide and methane flow control and regulation. The discrete components shall meet the technical standard of pressure, sealing, regeneration, replacement parts is convenient, reliable and other basic requirements. 6, the first use of desulfurizer desulfurization rate should be greater than or equal to 98%, total sulfur content ≥ 30%. Desulfurizing device can bear 10kPa pressure does not leak. Desulfurization reactor volume can be installed desulphurization of 2kg dose, (with desulfurizing agent 2kg). Should use ≥ 10KPa pressure and corrosion resistant materials, the wall thickness shall be more than 2mm, shall not use recycled materials. Sealing material should be flexible, and can wear. The structure should be easy to install and sorbent regeneration, reloading is convenient and ensure the sealing performance. Connecting pipe can be used inside diameter ≥ 10mm hose or other way and 16mm diameter (diameter 20mm) pipe matching, and can maintain the tightness. 7, the condenser should meet the following requirements: (1) water condenser volume > 0.5L. (2) the water condenser inlet and outlet pipe diameter should be greater than 6mm should be soft, PVC and 10mm diameter pipe closely. (3) structure: installation, convenient maintenance and ensure the sealing performance, with drainage device. (4): 10KPa sealing performance under pressure not to rupture. 8, soft PVC tube (1) material: PVC resin content of not less than 70%. (2) appearance: tube outer wall shall be flat, smooth, no depression, no discoloration decomposition line, impurities and other defects on the surface of impact performance. (3) color: color transparent (4) size: diameter 10mm, diameter limit deviation ± 0.3mm. The wall thickness of 1.5mm, the wall thickness deviation limit +25%. Note: according to the need to choose the hose and the inner diameter φ 10mm φ 12mm matching or. (5) physical and mechanical properties of A, the tensile strength is more than or equal to 14Mpa. B, elongation ≥ 200%. C, thermal aging tensile strength properties of A. rate (V1),%-20 ≤ V1 ≤ 20; B. elongation rate (V2),%-20 ≤ V2 ≤ 20. Requirements and customer service service quality assurance: 1, biogas accessories must have the test report of quality supervision, inspection and testing center of biogas products and equipment after the Ministry of agriculture in January 1, 2013, the product quality above. 2, the supplier is responsible for the installation, debugging or entrust the local conditional mechanism installation debugging and pay the factory installation costs $8%, installation and technical indicators to achieve the national standards. 3, one year repair and maintenance free.
