河南太锅锅炉生产制造的DZH型生物质木材锅炉是以生物质木材为燃料的新型高效低碳环保锅炉，生物质木材锅炉主要燃料包括木材、秸轩、水稻秆，薪材、椰壳 花生壳、瓜子壳、玉米芯、甜菜粕 树皮等所有废弃可燃的农作物，不需要额外加工可直接燃烧。也可使用煤炭燃烧实现两用。它的原材料分布广泛，成本低廉。生物质木材锅炉以低廉煤炭著称，是一种经济实惠的洁净能源锅炉。特别适用于环保要求较高，又有生物质资源的地区。
DZH型蒸汽锅炉为单锅筒纵置式水火管锅壳式锅炉，燃烧设备为活动炉排。炉膛左右两侧水冷壁为辐射受热面，炉膛两翼为对流受热面，锅筒内布置螺纹烟管，对流受热面，炉墙采用耐火砖砌筑部分采用耐热混凝土浇注捣制成型工艺，锅炉主机外侧为立体形护板外壳。
生物质锅炉特点：
1.采用拱型管板与螺纹烟管组成锅筒，使锅筒由准钢性体变为准弹性体结构，取消了管板区的拉撑件，减少了应力。管板内烟管由两回程改为单回程，解决了管板裂纹的难题。
2.锅筒下部由于布置了上升管排，消除了锅筒底部的死水区，使泥渣不易沉积，锅筒高温区能得到良好的冷却，预防了锅筒下部鼓包。
3.采用高效传热螺纹烟管，获得了强化传热
Introduction
Wood&coal fired moving grate steam boiler is single drum water tube and fire tube boiler, combustion equipment is moving grate. Water wall tubes at left and right sides of furnace are the radiated heating area. the two wings at furnace and screw fire tube in the drum are convection heating area. This wood fired steam boiler uses the upper drum, water wall tube and head are in symmetrical arrangement mode. The drum is welded assembly by cylinder and front back tube plate. This furnace structure in reasonable arrangement and high efficiency.
This wood fired chain grate steam boiler uses the new scientific achievement, such as arch tube plate, screw fire tube to solve the problem of tube plate flaw, water wall tube explosion, low efficiency, insufficient output, poor adaptability of different biomass fuel, improve the heat transfer.
The wood fired moving grate steam boiler could burn different types wood fuel, such as wood chips, wood block, wood baten, bark, bamboo filament, etc. The long wood (L≦2m) could burn without broken. Except wood fuel, it could burn other biomass fuels (bagasse, straw, waste cloth, etc.) as well. To avoid coking and improve combustion efficiency, adopts unique double secondary air design, to improve conditions of biomass fuel.
Products Advantages
1. High Quality Assurance
1) There is a professional design engineer team, before manufacturing, every boiler design drawing have to be approved by boiler and pressure vessel experts of CSBTS ( State Bureau of Quality Technical Supervision ), and then the boiler could be produced only if qualified.
2) To ensure the raw materials quality, all the steel plates are special-used for boiler with the Inspection Certificates. The raw material materials are inspected when entering factory, and only the qualified material could be put in storage and used for production.
3) To ensure the welding quality, there a professional welding team, including more than 30 senior welders. The welding materials are stored under constant temperature and humidity, to ensure the welding material quality.
4) The welding quality will be further examined during boiler manufacturing, by using x-ray detection, ultrasonic flaw detection, magnetic test, or penetration test, etc.
5) To ensure the boiler quality, the leakproofness and strength of pressure parts will be tested. The hydrostatic test is done to make sure there are no water drop or water mist leakage appear on steal wall or welding joint, no water leakage appear at the place of expansion, and no obvious residual deformation and abnormal situation.
6) To ensure no problems before boiler delivery, all the raw materials and boilers are supervised and inspected by the experts of Inspection Institution for Boiler and Pressure Vessel. There are international uality certificates of ISO 9001 and CE, we can also offer the inspection report of SGS, BV, etc., Quality Certificates, Energy audit report, and Energy Efficiency Test Report, etc.
2. Safety Assurance
3. High Efficiency Assurance
4. Professional Installation and After-sale Team
1) Professional engineer installation team offer the door to door installation and after sale service. The boilers will operate smoothly and safety, and you will get them without worries.
2) 24 hours hot-line to solve your problems, and offer the professional technical supports and after sale service in time to all over the world.
5. Convenient Maintenance
1) The chain grate is convenient for maintenance, it could be done without boiler shut down.
2) There are manhole, head hole, and special hand hole on the boiler, convenient for boiler internal installation, inspection and clean.
