SZL series biomass-fired steam boiler is package or shop-assembled water tube boiler with double steam drum and chain grate stoker structure. 4-6 tph boiler is package boiler and 6-35 tph is shop-assembled structure, which is composed of 2 parts, upper part is heat absorbing surface and lower part is combustion equipment. The former part of boiler body is surrounded by membrane wall, its upper part connects with boiler drum and lower part connects with header, which forms a combustion chamber to absorb the radiated heat from furnace; there are dense convection tube bundle between the back side of upper and lower drum, the high temperature smoke enters a separate economizer after flushing heat absorbing surface then discharge from chimney.

The new series is the first general-purpose ARM7 flash microcontroller to support full-load operation at 3.3V and 5V. The core processing performance is 54MIPS (at 60MHz), and it also has excellent energy-saving mode, STOP mode. The STANDBY mode current consumption is 12μA and 10μA, respectively, which makes it ideal for battery operation applications. Because it can be powered from a 3.3V or 5V battery, the new series offers maximum flexibility in an electrical noise environment without any additional cost.
The new STR750 series adds a number of innovative features that further extend the STR7 family's rich set of peripherals. For example, when the main clock stops running, the backup clock runs automatically, taking over the work of the main clock; the quick start function makes the device 55μs The code is started internally, and the device using the quartz crystal usually takes 1ms; the automatic wake-up function (Shuimuyuanhua-leading fault indicator AWU) can wake up the system from the low-power STOP or STANDBY mode without external signals or components; The 16-bit timer is extremely flexible and powerful; the PWM timer integrates three-phase motor control functions, simplifying the implementation of complex motor control such as vector control drive applications.
The communications serial port includes three high-speed (2Mb/s) UART interfaces that support the LIN protocol, and a serial memory interface that connects to external serial flash memory through glueless logic. Moreover, the STR750 family also includes a new mechanism that allows bit manipulation and masking to protect I/O pins.
"The new STR750F represents ST's deep technical strength in integrating ARM cores in system-on-chip solutions and standard microcontroller products, as well as our extensive proprietary intellectual property technology," Jim Nicholas, General Manager, STMicroelectronics Microcontroller Products “Therefore, the STR750F family is an unprecedented combination of high integration, performance and low power in the 32-bit embedded microcontroller market.â€
The early products in the series included approximately 30 product models with flash memory capacities ranging from 64KB to 256KB, and an additional 16KB read-write sync flash library for EEPROM emulation. The embedded flash memory features industry-leading data retention features and a 20-year data retention guarantee (85°C). These products include eight communication peripheral interfaces, including USB and CAN interfaces; the 4-channel DMA controller significantly reduces CPU load. These chips also include a fast 10-bit analog-to-digital converter (ADC). Some products in the range also expand the industrial temperature range to -40 ° C to +105 ° C.
Combining high integration, performance, low power, innovation and power rail flexibility, the STR750F family is an attractive general purpose microcontroller. In addition, because of the enhanced security features such as standby clocks, the new products are particularly suitable for a variety of embedded applications such as control panels, motor controls, data loggers, modems, printers and scanners, and cargo hoppers for alarm systems.
The STR750F series is equipped with a standard software library, a USB software library and an evaluation board. Two software libraries are provided to the user along with all peripheral low-level drivers; the evaluation board's demo board with USB interface, SMI, timer and an ADC, evaluation The board is also equipped with a JTAG connector, a motor control connector and a power supply. Third-party development kits are also available for purchase from IAR, Raisonance, Hitex, and Keil. These kits include a JTAG emulator, target board, and C compiler.
