coal oil cofiring steam boiler

9.4MW YQW gas-fired thermal oil heater for clean-energy industryThermal oil heater is a kind of new heat energy equipment with low pressure and high temperature, playing an important role in various industries. Huagang Gas Group is a sino-foreign joint venture enterprise, which established by Kunlun Energy Company Limited and Huabei Oilfield Company. The company is engaged in natural gas, liquefied petroleum gas, blast furnace gas and so on. Due to the stringent quality requirement for pipeline gas in China, all natural gas needs to be decarbonized and desulphurized. A high-quality coal cofiring steam boiler is one of the key equipment for the productive process. With the development of global environmental policy, the demand of clean energy is growing with each passing day. Huagang Gas Group has carried out public bidding to purchase one set of thermal oil heater to meet the production need. Relying on rich experience and powerful comprehensive technology strength, ZOZEN won the bid and provided 9.4MW YQW series thermal oil heater for them. The heat exchange surface of the thermal oil heater adopts multi-loop round coil tube structure, which features high security and sufficient heating surface. The waste heat boiler, air pre-heater and economizer are installed on the tails of the thermal oil heater to effectively improve the thermal efficiency (The thermal efficiency of ZOZEN thermal oil heater can reach up to 95%). Moreover, this kind of thermal oil heater adopts perfect running control and safety monitoring device, which can control working temperature strictly and guarantee the safe operation.

PRODUCT INTRODUCTION fuel gas-fired boiler fuel gas-fired boilers and coal-fired coal cofiring steam boiler is not the same, gasoline and diesel and gas-fired burner must be poured into the fuel to the boiler furnace using a combustion chamber rather than grate facilities. Since the fuel gas-fired boiler is not easy to cause the fly ash lit, so no oil or gas boiler slag removal equipment. If mixed with air or exterminate within a certain range, it is introduced into the furnace petrochemical and gas easily the explosive. Thus, any gasoline and diesel and gas-fired boilers must be selected and automatic combustion control system. Compact boiler fuel gas, and the small boiler exhaust, drainage, control and auxiliary equipment installed at the distribution panel, and produce large and small boiler assembly. Fuel gas-fired boiler safety valve installation key point describes the installation of fuel gas-fired boiler safety valve sure to carry out in accordance with reasonable installation process, to prevent wrong and lead to risk. Fuel gas-fired boiler safety valve installation should pay attention to what matters? The following is a brief description: 1 oil-fired boiler safety valve having a lever bar to avoid self-weight and the mobile device guide body defining deviant lever, the spring valve lift handle and avoid the need for screw adjustment means random twist. 2. Rated evaporation than 0.5t / h gas boiler safety valve should be arranged at least 2, Rated evaporation gas boiler should be equal to or less than 0.5t / h, fitted with at least one safety valve. Separable economizer outlet and a steam superheater outlet valve should be installed. Sectional area of ​​the connecting pipe between the boiler safety valve 3. Fuel gas boiler can not be lower than the imported cross-sectional area of ​​the valve. If several valve mounted on each stub is directly coupled to the drum, the passage sectional area of ​​the stub is less than 1.25 times not all of the area of ​​the exhaust valve. 4. Oil and gas boiler safety valve should be mounted vertically in the height of the boiler drum and the header. Can not be mounted between the valve and the steam outlet conduit and the valve drum or header. 5. For rated steam pressure less than or equal to 3.82MPa boiler safety valve throat diameter of not less than 25 mm; the rated steam pressure is greater than 3.82MPa boiler safety valve throat diameter of not less than 20 mm. 6. Fuel gas boiler safety valve should normally be established an exhaust pipe, the exhaust pipe should be directly connected security grounds, and there is sufficient cross sectional area to ensure the smooth flow of the exhaust gas. The bottom of the valve should be equipped with an exhaust pipe connected to the drain of a safe place. Valve must not be installed in the exhaust pipe or drain pipe.

Stalk Biomass fired coal cofiring steam boiler is one kind of biomass fired steam boiler too. This biomass fired steam boiler can use fuel like crop stalks, rice stalks, wheat stalks, oil seed rape stalks, etc. Thus, stalk fired steam boiler also lists as one of agro waste fired steam boiler. ZG manufactured biomass fired steam boiler also can be divided into CFB steam boiler and chain grate steam boiler. Here, we would like to introduce Biomass stalk fired steam boiler, a kind of chain grate steam boiler in structure design. Stalk fired chain grate steam boiler can also be divided into single drum biomass fired steam boiler and double drum biomass fired steam boiler. Stalk fired steam boiler also can be classified into horizontal biomass fired steam boiler and vertical biomass fired steam boiler or corner tube biomass fired steam boiler. In a word, ZG Boiler has widely products to supply, with different structures and designs.
