All equipment (includes boiler proper, economizer, burner, valves, instrument, electric control cabinet, chimney, water treatment, soft water tank, energy-saving circulating pump, raw water pump, deaerator, etc.) is designed to be installed on one or two prepared concrete bases. Skid mounted boiler has all interconnecting piping completed and has passed the cold state test at the factory before delivery. After the boiler arrives at the site, it only needs to be connected to water, electricity and gas to operate.
The boiler body of WNS series boilers adopts wet-back structure. The combustion, water level, temperature and steam pressure of the boiler are automatically adjusted and protected, which can realize fully automatical operation to ensure safety and reliability. The large-diameter corrugated furnace of this boiler ensures sufficient combustion of natural gas. Combined with an advanced low NOx burner, it can easily achieve the requirement of NOx≤30mg/Nm3. In addition, the boiler is also equipped with energy-saving equipment at the end of the boiler flue, so that the boiler thermal efficiency can reach over 98%.
SZS series boiler is designed with longitudinal double drums and " D " type chamber structure. The furnace is on the right and convection tube bank is on the left. The body is fixed on the basement by middle and both end flexible supports and make the boiler expand horizontally sideways. Around the furnace is membrane wall. Furnace and tube bundle are totally separated by the membrane wall at the left side of the furnace. The back part of convection tube bank is sparse shift structure, front part is aligned structure. Smoke from furnace outlet enters re-burning chamber, convection tube bank area, and then from left front part enters spiral fin coil economizer and condenser, and finally is discharged to atmosphere through chimney.
Steam boilers play a key role in the production process of dye intermediates, proving steam for synthesis, drying and other processes. SZS gas-fired water tube boiler adopts the structure of membrane water wall for better sealing effect and higher thermal efficiency; In addition, to effectively reduce the NOx emission, the boiler is equipped with a large volume furnace and an advanced NOx burner imported from Europe, so the NOx emission can reduce to 30mg/Nm3.
People cannot live a comfortable life without heating boilers in the winter, the normal and stable heat source is of great importance to human life. What is following is the increasingly serious problem of environmental pollution, implementing the policy of “coal to gas” is no time to delay, using gas-fired hot water boilers has been the general trend.
This series of boilers adopts the design of " D " type membrane wall structure, the steam drum, the water drum and convection tube bundle form the convection heating surface to ensure the the boiler expands on both ends as a whole; at the same time, the combustion chamber is designed with the narrow distance tube membrane water cooling wall to reduce heat lost, in addition, the boiler is equipped with a big combustion chamber for the full combustion of fuel, effectively increasing the boiler thermal efficiency over 98% and reducing the NOx to 30mg/m³, which are superior to the national level one energy efficiency standard.
