Introduction

  SHL series of boiler is the bulk industrial boiler with dual boiler cylinders and transverse arranged, as well as the natural cycling water pipe boiler. The transverse upper and lower boiler cylinders and water cooling pipe walls together form the silo type furnace, together with convection pipe bundle and collection chest to form the boiler body frame. At the rear part, there is a coal saver air preheater, It is available to set up superheater inner furnace. The combustion equipment is squama grating, free timing control. Exit shop in bulk type for site assembly and construction, The smog flow is a type of multi-backhaul.

  This type of boiler has the following characteristics: capable of over duty quick in temperature rise, high in heat efficiency, less land keeping; squama grating makes greatly enhauced reliability in performance, Furnace arch and wall can be built in casting way, good in block out performance which betters ignition conditions, environment protective and energy saving,fierce combustion,high extent in automation,stable in performance sate and reliable,together with very long working life.

  This type of boiler features are in sufficient output and high efficiency,safe and reliable,good in duster and de-smog and etc.​

Features

  1. Membrane water wall structure is adopted on both sides of the hearth, which not only ensures the sealing of the hearth, but also improves the thermal efficiency of the boiler.

  2. In the SHL series bulk chain grate boilers, the soot blower interface is reserved for the convection tube bundles of the biomass boilers and the heating surface of the economizers. Special fuels (especially those with strong adhesion) can take necessary measures to prevent them.

  3. The furnace arch adopts a water-cooled arch structure, which not only increases the rigidity and stability of the furnace arch, but also prolongs the service life of the furnace arch.

  4. Using the improved GEF special deslagging technology; grate adopts a new type of small-scale grate slice, adding a unique insurance ring, completely customer service problems of the grate sheet falling off, effectively reducing the grate leakage, so that the grate is stable and reliable , greatly improving the combustion efficiency.

  5. The grate adopts the optimized structure of the separate air chamber independently adjusted by double air supply, which effectively meets the combustion of the fuel into the furnace.

  6, the use of unique secondary air structure, effectively improve the air force field in the furnace, the hot particles lead to the front arch, is conducive to the ignition of the fuel ignition, but also extend the residence time of the fuel in the furnace, Increased fuel adaptability and utilization.

  7. The SHL series bulk chain grate biomass boiler grate adopts the double-layer or single-layer arrangement, which better meets the actual needs of users.

  8. There is an economizer and air preheater at the tail; a superheater can be installed in the hearth, the combustion equipment is a scale grate, stepless speed control, bulk delivery, on-site assembly and masonry, and the flue gas flow is multi-return .

  9, the boiler has excess capacity. Warming up, high thermal efficiency, small footprint;

  10. The grate adopts flake-type grate, which greatly improves the operational reliability; the furnace arch furnace wall can be poured.

  11. Good sealing performance, improved fire conditions, environmental protection and energy saving, strong combustion, high degree of automation, stable operation, safety and reliability, and high service life.

  11, this type of boiler has sufficient output, high thermal efficiency, safe and reliable, eliminate smoke and other characteristics
