For the biomass fuel boiler pressure parts,the water side is mainly electro chemical corrosion,the fire side (or flue gas side) is mainly chemical corrosion.The oxygen corrosion belongs to electrochemical corrosion, it is mainly caused by the dissolved oxygen in water.At room temperature,the dissolved oxygen concentration is about 9.1mg / L,according to the GB1576-2001 “industrial boiler water quality” requirement ,the rated steam pressure should not be more than 1.0MPa,the dissolved oxygen concentration should not be more than 0.1mg / L,otherwise,it is likely to lead to metal corrosion.
10 tph WNS series gas-fired fire tube boiler project for chemical industryChangchun Huatao Automotive Plastic Trim Co., Ltd. is an auto parts company mainly engaged in the production of automotive plastic inner and outer trim parts, epp foam parts and engine plastic parts. With its technical advantages, it has reached cooperation with Toyota, FAW Volkswagen and BMW. In the production process of automobile injection molded parts, many processes such as feeding, plasticizing and mold filling have a certain temperature requirement. The boiler as a heat source device plays an important role in its production line.In the face of the increasingly severe environmental protection situation, Changchun Huatao actively responded to the "coal to gas" policy and planned to introduce energy-saving and environment-friendly boilers. After a series of investigations and comparisons of many boiler manufacturers, Changchun Huatao finally purchased ZOZEN's star product of environmental protection - WNS series gas-fired centrifugal design fired steam boiler. This series of condensing gas-fired boilers is horizontally arranged, compact in structure and small in floor space. The combustion chamber adopts a large-diameter corrugated furnace to reduce the thermal stress and enhance the smoke disturbance, therefore, improving the heat transfer effect. with the advanced low NOx burner, the NOx emissions can be as low as 30mg/Nm3. The spiral finned tube economizer is also installed at the tail of the boiler to reduce the exhaust gas temperature to 60 degrees, and the boiler thermal efficiency can be over 98%. In addition, the boiler's fully automated control system features automatic operation and interlock protection, which meets the requirements for safety and environmental protection of Changchun Huatao production line.

Continuous automatic adjustment of water supply, drum, induced draft fan damper flap opening remote control, remote pump control valve (an intake gas boiler control valve), a heavy oil combustion boiler should automatically adjust the oil, gas boiler should automatically adjust the air pressure, there is superheater boiler there should automatically adjust the temperature of superheated steam. 3) alarm and protection. High and low water level indication and alarm, low water level limit protection, over voltage protection and alarm indication of heart steam, oil accident alarm system, furnace flame protection, fuel gas overpressure protection or low temperature alarm and protection. Boiler superheater should have more limited temperature of superheated steam and an alarm indication. 4) control and the other. Drums, Fan, and start and stop the pump interlock control program, drum, fan baffle opening damper indicated, shall be provided with explosion-gas boiler electrical control equipment.
Hot water boiler in the school dormitory and classroom building are generally used for central heating, drinking water and bathing water aspects of teachers and students and so on. Shanxi Linxian County high school is an important educational school personnel training for the community. 2017, the school responded positively to national coal to gas and other environmental policies, but also to provide students with a more favorable living and learning environment, the school decided to phase out conventional coal-fired boilers, clean and environmentally friendly replacement for the gas boiler. After getting to know and choose the boiler industry, major companies, determined cooperation with professional production of clean fuel boiler fast boiler-by-side to provide a fast 4.2MW integrated condensing gas hot water boiler (WNS4.2-1.0 / 115 / 70-YQ).
Our engineering team designed a threepass fire tube steam boiler with a capacity of 5000 kg of steam per hour and a operating pressure of 10 bar. The Figure below equations shows a standard three pass fire tube steam boiler system used as a template for our engineering teams design.Get A Quote
SZS series condensing type oil(gas) fueled boiler is of double drum and D-type structure. The overall design of full-membrane wall can surround and seal high temperature flue gas. which overcomes the defect of smoke leakage due to incomplete sealing often occurred in conventional boiler, so as to ensure efficiency and safe operation of boiler.Get A Quote
Conventional PF coal-fired boilers, currently being used in the power industry, use air for combustion in which the nitrogen from the air (approximately 79% vol) dilutes combustion products such as CO 2 and water vapor in the flue gas. During oxyfuel combustion, a combination of oxygen (typically of greater than 95% purity) and recycled flue gas is used for combustion of the fuel.Get A Quote
